LX2160A RDB-B (SN: TR21420689) won't boot and can't connect Lauterbach

[ajedgar]

Hi,

We have gotten ourselves into a situation where the console is not showing anything on boot and we also can no longer connect the Lauterbach.

When we power up the board there is no console output at all and when we attach the Lauterbach it says:
  B::SYStem.Mode Up
  debug port fail

We got into this situation by updating the bl2_flexspi_nor.pbl at offset 0x0000 in the flash, that booted but gave an authentication error, then we tried bl2_flexspi_nor_sec.pbl, and it really did not like that. It was after flashing that, that the board seems to be bricked.

We have tried setting SW1[6:8] to '001' to boot from bank1 of the flash but that made no difference.

What is the best way for us to un-brick this board and get back to work?

Thank you very much in advance for your help!

Please prepare SD boot environment on you host PC.

$ wget https://www.nxp.com/lgfiles/sdk/lsdk2108/firmware_lx2160ardb_rev2_sdboot.img

$ wget https://www.nxp.com/lgfiles/sdk/lsdk2108/flex-installer && chmod +x flex-installer && sudo
mv flex-installer /usr/bin

$ flex-installer  -f firmware_lx2160ardb_rev2_sdboot.img -d /dev/sdx

Note: /dev/sdx is SD device name on your host PC.

Then plug in SD card to your target board and configure the switch setting for SD boot.

The switch setting:

That worked.

Thank you!
