RT5350 Stop the system process

stm32 · April 19, 2020, 1:31am

Hello.
I have a HLK RM04 32Mb module. I uploaded the version through openwrt website Bleeding Edge, r38333.
But I have a problem I can't openwrt update to the latest.
Did not work commands:
opkg update
wget -O /tmp/a.bin
Winscp uploading does not work either Openwrt hangs. Under the RS232 console, I see how the system starts to load processes and resets during the upload process.
I tried to upload a new openwrt in failsafe mode, but then the ethernet ports do not work - I can't connect to winscp.

Kilning processes to relieve the system also does nothing. When uploading the new openwrt, the module also resets. Anyone have any ideas for uploading a new openwrt? Or restoring the original HLK software?
Thank you in advance.
Ps. Sorry for the translotor

Is this your device?
I am not sure which version is this. Snapshot is at r13013 and there is 19.07.2 stable release for this device.

Ancient OpenWrt master snapshot sources from about October 2013. Bleeding edge r38333 matches that...
(Commit counting restarted in the LEDE split, but that 38333 is from the old count)

(The quote also shows that log output was copy pasted to shell, making confusing reading of the execution attempts...)

My mode is this one HLK
Any ideas on how to update this to openwrt 19.07?
When I try to upload a new openwrt, the module resets.

RAM is going to be tight. Do not opkg update as you don't need the package list prior to replacing the OS. Use free to see how much RAM there is. Unnecessary services will need to be disabled, you can't just kill their process as they will restart.

Maybe manually flash from the bootloader?

stm32 · April 19, 2020, 4:39pm

Can you say more about this manual flash bootldoer?
Do you mean desoldering flash bones and programming them with an external programmer?

mk24 · April 19, 2020, 5:17pm

No, using the serial port to the u-boot bootloader console.

stm32 · April 19, 2020, 8:43pm

U-boot is disablle on this model. HLK

Outdated approach
There is not a simple way to run OpenWrt on this tiny module, because Hi-link disabled uboot. Therefor we can solve this by finding a Hi-Link compatible firmware for it.

For example of *Hame MPR-A1*:

Solder out the Hame MPR-A1's 4M flash, then just copy all 4M content.
Solder out the Hi-Link's 4M flash, write the MPR-A1's 4M firmware to it.
Solder back the flash, Now the Hi-Link HLK-RM04 performs like a MPR-A1, and more information here.

I think it's best to re-program W25Q128 via SPI in raspberry pi.
Openwrt HLK RM04 https://openwrt.org/toh/hilink/hlk-rm04
Can I upload the squashfs-factory.bin file right away? Do I have to play first?
uboot256.img and then start the u-boot press 2 and upload the file with the extension bin through tftp.?
