HCL stuck in U-Boot after update


Question

I initiated an update of the HCL via the App a few days ago. After that the contact was lost.
I have tried all recovery options I have found with no luck.

I opened up the HCL and discovered the AM3354 module inside.
I then found the console port (3pins: 0V, Rx and Tx. 3.3V level signals) and see that it is stuck in U-Boot:

It stops in U-Boot as there are some memory failure, but it does not respond to any known command.

It reboots every 8th minute.

 

The LEDs are flashing as in recovery mode, but HCL is not visible on the net and and it does do not respond on 192.168.81.1 when PC is connected directly.

I find that a bit strange. Is U-Boot really holding the recovery web server?

 

If command interface had worked, it could maybe be possible to restore the on board flash using TFTP.

easier than you might think, this is the SOM used in HCL https://grinn-global.com/site/assets/files/1665/chilisom_datasheet.pdf   (actually this is the v1.1 used on HCL, no idea how many changes

P2 header, near LAN. If the U12 on the bottom side (near P2 header) is not populated, you will need to solder two bridges (not between middle pins ...)   1 - <----> - 6 2 -       

generally you can boot from lot of source, if you manage to set it:   https://processors.wiki.ti.com/index.php/AM335x_board_bringup_tips https://processors.wiki.ti.com/index.php/The_Boo

ow on Tera term      CCCCCCCCCC.....  in UART mode.

 

now in Tera term     FILE  --->transfer ---> xmodem ---->send ---- >  hcl_u-boot_spl_2011.09.00000.img

after install

 FILE  --->transfer ---> ymodem ---->send ---->hcl_u-boot_2011.09.00000_bootdelay.bin 

 

then it start to work

in my network settings  192.168.81.5

                                             255.255.255.0

                                             192.168.81.1

 

I can't open on browser 192.168.81.1 and nothing. I can see Lan is up -->HCL-004601 login: [  124.074371] PHY: 0:00 - Link is Up - 100/Full

 

Any ideas ?

This is the board boot. If u hold the recovery button - it will boot recovery

Then you can flash 4.520 for example (with exploited security hole) and using the root exploit - flash custom recovery

When you have custom recovery (its also has root:hc2 serial/ssh login), its possible to flash custom firmware

How can I instal boot loader? My dont start. I Can run via Uart buy after unplug power my fibaro no start. 

I have also broken recovery . That's is really problem because I cant reset password to instal custom recovery . Do you have SD card system? Then I Can run From SD instead NAND

 

 

 

after connections power I only have black screen.  only connecting the left side of the resistor R9 causes the appearance of CCCCC.

 

 after loading your files, I come to the login 192.168.81.1 but do not accept my password.  disconnecting the power means that I have to upload files again.

 

 by pressing the plus button and uploading your files it starts running recovery but not quite.  My logs on the previous page From recovery

When I did it 

ow on Tera term      CCCCCCCCCC.....  in UART mode.

 

now in Tera term     FILE  --->transfer ---> xmodem ---->send ---- >  hcl_cr_v10.img

after install

 FILE  --->transfer ---> ymodem ---->send ---->hcl_u-boot_2011.09.00000_bootdelay.bin

 

System boot(you can see my log on UART), I plug Lan cable and set IP, but can't connect 192.168.81.1. Scan IP and nothing.

 

Try recovery mode (https://manuals.fibaro.com/knowledge-base-browse/recovery-mode-on-home-center-lite/) nothing. I can't upload custom firmware. 

 

How after UART file upload and system URAT boot can find IP and upload custom firmware?

1. Connect HCL to default place (HCL was worked)

2. ow on Tera term      CCCCCCCCCC.....  in UART mode. now in Tera term     FILE>transfer-> xmodem >send >  hcl_u-boot_spl_2011.09.00000.img

after install

 FILE->transfer-> ymodem ->send->hcl_u-boot_2011.09.00000_bootdelay.bin

3. IT is boot, on UART you can see IP. On browser enter IP.

 

I can see this 

 

 image.png.d051c847bdc75bf064505885803fdecf.png

 

 

 

Try  script hcl_4140_root.py

 

get error 

 

=============== RESTART: C:\Users\user\Desktop\hcl_4140_root.py ===============
Traceback (most recent call last):
  File "C:\Users\user\Desktop\hcl_4140_root.py", line 2, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

 

Where is error?

Hi!

 

My recovery root is damaged and by playing with the u-boot I managed to erase the recovery kernel too. Now I am left only with the normal kernel and the normal root. Although the device boots in normal mode ok, I cannot boot into recovery at all.

 

Can one of you please help me with a nand image of the recovery kernel that I can flash via u-boot? And ideally (but there is little hope with this one) the recovery root image?

 

Thanks!
