Short description how to upgrade router with 32 MB on board.

Body:
PCB is exactly the same, only resistor to set mem size to 32m has been added.
Bootloader
Default u-boot bootloader is not fully functional, and it seems that it is protected against starting other firmware than oryginal one.
Do not try to upgrade this bootloader from bootloader menu - you will brick your device !
To load openwrt firmware new bootloader is needed - I am using - uboot256.img taken from JiapengLi
Openwrt firmware
Do not try to upgrade this bootloader from bootloader menu - you will brick your device !
To load openwrt firmware new bootloader is needed - I am using - uboot256.img taken from JiapengLi
Openwrt firmware
Default firmware cannot accept openwrt images so at the beggining (after u-boot upgrade) we will load minimal openwrt firmware mini.bin .
Upgrade procedure
Verification
Check twice if it is router we are talking about:
- Take a look on photos of PCB
- Check MDT structure by call "cat /proc/mtd", has to be like below:
cat /proc/mtd
dev: size erasesize nameThink twice :)
mtd0: 00400000 00010000 "ALL"
mtd1: 00030000 00010000 "Bootloader"
mtd2: 00010000 00010000 "Config"
mtd3: 00010000 00010000 "Factory"
mtd4: 003b0000 00010000 "Kernel"
First step
- Reset router to default settings
- Connect to router via telnet and login with default user name (admin) and password (admin)
- Now you can upgrade router via FTP or USB
Upgrade via FTP
- Cceck free memory
- Verify free memory by calling free, check if you have more than 3500 free memory
# free total used free shared buffersMem: 28584 17128 11456 0 0Swap: 0 0 0Total: 28584 17128 11456
- Resize TMP, and start proftp server
mount -o remount,size=4M tmpfs /tmp
proftpd.sh server 192.168.100.1 192.168.100.1 21 10
proftpd
- Connect to router via ftp and copy uboot256.img and mini.bin to /tmp directory on router
- ! Upgrade uboot - be careful, do not reset router during and after this operation !
mtd_write write /tmp/uboot256.img Bootloader
- You should see on console
#Unlocking Bootloader ...
#Writing from /tmp/uboot256.img to Bootloader ... [w]
- ! Upgrade firmware - do not reset router during this operation!
mtd_write write /tmp/firmware.img Kernel
- You should see on console
#Unlocking Kernel ...
#Writing from /tmp/mini.bin to Kernel ... [w]
- Reboot router :), enjoy new u-boot with working ethernet and openwrt firmware. Now you can use standard openwrt upgrade procedure.
reboot
- Router will set IP address to 192.168.100.1 , you can login via telnet
Upgrade via USB
proftpd.sh server 192.168.100.1 192.168.100.1 21 10
proftpd
#Writing from /tmp/uboot256.img to Bootloader ... [w]
#Writing from /tmp/mini.bin to Kernel ... [w]
- Prepare usb stick, format it with fat filesystem, and copy uboot256.img and firmware.img
- Conect usb stick to router and mount it by:
mount /dev/sda1 /mnt
- Wait a few seconds and verify if you see files
ls /mnt
- You should see content, do not go further if you do not see files !
uboot256.img mini.bin
- ! Upgrade uboot - be careful, do not reset router during and after this operation !
mtd_write write /mnt/uboot256.img Bootloader
- You should see on console
#Unlocking Bootloader ...
#Writing from /mnt/uboot256.img to Bootloader ... [w]
- ! Upgrade firmware - do not reset router during this operation!
mtd_write write /mnt/mini.bin Kernel
- You should see on console
#Unlocking Kernel ...
#Writing from /mnt/mini.bin to Kernel ... [w]
- Reboot router :), enjoy new u-boot with working ethernet and openwrt firmware. Now you can use standard openwrt upgrade procedure.
reboot
- Router will set IP address to 192.168.100.1 , you can login via telnet
#Writing from /mnt/uboot256.img to Bootloader ... [w]
#Writing from /mnt/mini.bin to Kernel ... [w]
Many Thanks for martin4android for support and materials.
I have same router with 32Mb of RAM. But it has reduced busybox with only 10 commands: clean, ping, traceroute, ipmac, quit, show, restart_httpd, restore_defaults, ated. So I can't flash it using this manual. The only way to flash is to do it from web-interface or using bootloader menu.
ReplyDeleteI flashed it successfully using UART cable from u-boot menu and tftp connection (I did not change u-boot, only firmware).

Good afternoon.
ReplyDeletePlease.
Take a picture of your Mini USB Portable
I wanted to see how the resistors installed
I want to change the memory from 16mb to 32mb
I want to remove my chip em639165ts-6g
I want to put a chip em63a165ts-6g.

I want to put Openwrt in my Mini USB Portable
thank you

SMD components are not marked, what resistor do you want me to measure?
DeleteHi. I buy a 16MB variant. Flash new uboot128 and openwrt. Everything work good, but 16MB ram is not good for work with wifi.
ReplyDeleteI buy 32MB chips and solder it to the router. I solder 3,3K resistor for detection 32MB ram..... but only 16MB is detected on uboot and kernel. How can I flash uboot256 to the device? MTD partitions have other names, but adresses are same as factory... but if i try write to MTD, i have this error
root@OpenWrt:/tmp# mtd write /tmp/uboot256.img u-boot
Could not open mtd device: u-boot
Can't open device for writing!
Please help me.. I spend lot time with desoldering and soldering ram chip, and I was sad when I see only 16MB ram and wifi make reboots and out of ram.
Hi, have you try images mentioned here http://my-embedded.blogspot.com/2014/01/mini-usb-portable-3g4g-router-rt5350f.html ?
ReplyDeleteprovide output of : cat /proc/mtd
Доброе время суток! Ребята у меня накрылся роутер после неудачной прошивки. Все время горит красная лампочка и не как не могу вернуть его к жизни. Пытался через telnet, устанавливает, загораеться синяя лампочка. Но не реагирует.. После выключения питания заново загораеться красная.
ReplyDeleteHave you setup IP on PC to for example 192.168.100.10 and connect to router ip 192.168.100.1 ? I am asking because some forget that router after restart have fixed ip 192.168.100.1 and no dhcp.
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteЯ выставлял на сетевой карте 192,168,100,2 и пробовал прошить прошивками указанами выше. Только после прошивки роутера, загорелась синяя лампочка. Жду 5 минут, перегружаю и снова красная.... Сейчас попробую изменить ip.
ReplyDeleteУ когото есть официальная прошивка?

ReplyDeleteHi, I also bought a 16MB one(precisely equal to the pictures shown here) and followed your instructions by downloading uboot128.img and firmware.img from http://rcc.googlecode.com/svn/trunk/projects/rt5350_mini_router/img/ and putting it on a USB stick. All seemed to go as described. However, despite being able to telnet:
ReplyDelete1 - There's nothing listening on port 80 (so, no web interface)
2 - ls /dev doesn't show any sda1 device (so, no access to USB stick)
3 - proftpd.sh doesn't seem to exist (so, no FTP)
There doesn't seem to be an easy way to flash a different firmware. I already placed an order on a UART cable, but I'll have to wait a couple of weeks for it to get here. Is there anything I can do while I wait? What have I done wrong, and how can I recover from it?
Thanks in advance.
Hi, after some trial and error I managed to get the firmware into the router with wget from a tiny web server on my PC. However, everyone seems to agree that 16MB is too short for using lan+wifi. I wish I could flash it with Hame A15 firmware... :(
ReplyDeleteHi Pablo,
ReplyDeletein mini.bin only telnet is included. If you would like more services, download appropriate image from http://rcc.googlecode.com/svn/trunk/projects/rt5350_mini_router/img/.
But with 16 MB web interface is not stable, until you will not enable swap on USB stick or upgrade RAM to 32MB, the same issue is with WIFI.
Hi,
ReplyDeleteI've got 4x very similar devices (but not quite) and wondered if you could give me some pointers!
Initially they had the limited shell "BoC Router", but these devices have more holes than swiss cheese so happily have a full busybox instance now :)
RAM = em63a165ts-7g (32mb) (143mhz vs 166mhz of the -6)
Flash = pm25lq032 (4mb)
# cat /proc/mtd
dev: size erasesize name
mtd0: 00030000 00010000 "Bootloader"
mtd1: 00010000 00010000 "Config"
mtd2: 00010000 00010000 "Factory"
mtd3: 003b0000 00010000 "Kernel"
mtd4: 003b0000 00010000 "Romfs"
mtd5: 003b0000 00010000 "Firmware"
...
Warning: un-recognized chip ID, please update SPI driver!
AT25DF321(1f 47000000) (4096 Kbytes)
mtd .name = raspi, .size = 0x00400000 (4M) .erasesize = 0x00010000 (64K) .numeraseregions = 0
Creating 6 MTD partitions on "raspi":
0x00000000-0x00030000 : "Bootloader"
0x00030000-0x00040000 : "Config"
0x00040000-0x00050000 : "Factory"
0x00050000-0x00400000 : "Kernel"
0x00050000-0x00400000 : "Romfs"
0x00050000-0x00400000 : "Firmware"
So different flash and a weird looking MTD layout.
I've never really dabbled with OpenWRT so any pointers you could give me in mapping these (presumably to a modified mpr-a1 dts?) and building an image - it would be much appreciated!
Thanks again.

DeleteHi,
ReplyDeletehard to help, you have to start lstuddy openwrt build system, setup development environment and start to play.
A couple of weeks of studying, playing and reverse engineering parts of the original firmware - and my patch has now been accepted into trunk.
ReplyDeletehttps://dev.openwrt.org/changeset/43102/trunk
Just flash from the GUI :)
Please, it is possible upload somewhere this your firmware? Thank you.
DeleteI have a 32M clone with bad uboot - cyclic network drops with illegal image, so i cant update uboot or data via tftp.
ReplyDeleteTIMEOUT_COUNT=10,Load address: 0x80100000
Loading: *
ArpTimeoutCheck
T T T T T T T T T T
Retry count exceeded; starting again
Trying Eth0 (10/100-M)
ETH_STATE_ACTIVE!!
any clues?
Self response: if anyone flash wrong bootloader (via uart-tftp) and catch network loop-down and impossible to flash anything, u may dont desolder flash and have a sex with spi. just use kermit and uart:
ReplyDeleteon uboot side select 7 (flash uboot via kermit)
on linux host side run and configure c-kermit:
set port /dev/ttyUSB0 (or your tty-uart node)
set speed 57600
set carrier-watch off
set flow-control none
set prefixing all
send /path_to_correct_uboot_image
wait some minutes and viola!

Have anyone measure the power consumption for this device.
ReplyDeleteI'm planning to use a 3G dongle Huawei E173, and power it from a solar/battery station.

ReplyDeleteHello, I've got a problem concerning the IP address: you say that the IP is 192 .168. 100.1 after reboot, however when I try to manually set my IP to 192.168.100.2 the router cannot be found. DHCP on ethernet does not work either.
ReplyDeleteAny help ?
Actually it does work, it was just a question of netmask and gateway.
ReplyDeleteMine did not have ftp but samba. So I did put the file setting up samba :
ReplyDeletesamba.sh hostname WORkGROUP
smbpasswd admin admin
samba_add_dir.sh tmp /tmp admin
smbd
nmbd
then access \\192.168.100.1\tmp with login admin admin
Hi, the img and bin files are no longer available (404). Can you please upload them somewhere?
ReplyDeleteproftpd does not exist on the board
ReplyDeletenone of the image files mentioned still exist on the web.
ReplyDeleteI used images from http://ofmodemsandmen.com/download/GoldenOrb/a5-v11-GO2016-04-01.zip.It contains all.Also check OpenWrt page
ReplyDeleteMy device stopped booting during a when i insert a USB-Serial adapter.No blinking of LED when power up.Is it bricked or damaged?
