Hi,
I am using the OMAP353x EVM board Rev G from Mistral with 256Mb Micron Nand chip. The package already installed coming with the board was OMAP35x-PSP-SDK-02.01.03.11. I followed the procedure for upgrading the x-loader, u-boot.bin and kernel by TFTP but after upgrading the kernel it uncompress and I lost the console, LCD as well the serial port like you can see below on the trace. However, if I plug the usb otg cable the PC react proving that kernel is running.

I suspect my bootargs are incorrect.

There is something wrong with my environment settings?
Thank you,
