Other Parts Discussed in Thread: TMDSEVM572X
Hi,
SDK: ti-processor-sdk-linux-am57xx-evm-06.03.00.106-Linux-x86-Install
The customer uses a customized board. The difference between the customized board and TMDSEVM572X is that customized board has only 1G memory, the default network port is eth1, and other peripheral connections are the same.
So customer modified the memory of uboot to 1G and the network port to eth0, recompiled to generate MLO and u-boot.img, replaced the file of the same name in the sd card boot, and didn't make any changes to the rootfs partition. After booting up, kernel stuck in waiting for root device PARTUUID=7a61ff61-02...
Below is the boot log:
