Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: AM3358

Tool/software: Linux

I have 2 AM335x Evaluation Module and I tried to boot then following Quick start guide instructions.

I used the SD card with its original image.

In serial output I had the following:

CCCCCCCCCCCCCCCC
U-Boot SPL 2014.07-g7e537bf (Feb 11 2015 - 08:15:16)

and then it breaks,.

I Downloaded ti-processor-sdk-linux-am335x-evm-04.02.00.09-Linux-x86-Install.bin from TI web page. After installing it I run create_sdcard.sh script that have successfully finished.

When I try to boot using the sdcard just written the outputs was CCCCCC....

Does anyone have an idea about this issue?

What is the GP EVM main board revision? Have you set the profile switch and sysboot switch correctly?

Hi Biser,

Main board is an AM335x ZCZ Base Board REV 1 6A with AM3358 processor.

I have set sysboot 8-15 (sw4) as 11111101, 0-7 (sw3) as 01111111 and profile as 0000. 0 means switch in off position and 1 in on position

Thanks for your help.

Regards,

Rodrigo

Please refer to this wiki for SW3 and SW4 settings: processors.wiki.ti.com/.../AM335x_U-Boot_User's_Guide
Note that these switches are inverted on the GP EVM (i.e. ON is actually OFF and vice versa).
