Hello,
I have an AM572x Evaluation Module TMDSEVM572X and a SD card containing Linux PSDK 6.03. The EVM was working fine until today, when I connected it to power, it did not come up. I checked for console prints via minicom and found following -
U-Boot SPL 2019.01-g333c3e72d3 (Apr 20 2020 - 04:15:00 +0000) DRA752-GP ES2.0 Trying to boot from MMC1 Loading Environment from FAT... *** Warning - bad CRC, using default environment Loading Environment from MMC...

After this, the kernel starts and I get a login prompt -

But LCD does not show anything. Weston won't come up. If I try to start Weston manually, I get following -
root@am57xx-evm:~# /etc/init.d/weston restart Stopping Weston Starting Weston Waiting for input device...
I think the LCD device is not instantiated. But It was working till yesterday. Is ti possible because of loose connections? I haven't disturbed the connections on the board.
I tried using the same SD card on other AM5728 EVM, and it works completely fine.
Please suggest.
Thanks & Regards,
Devashish
