PROCESSOR-SDK-AM335X: Booting Problem

Vamsi Siddhani

We have a custom board based on AM335x EVM & Starterkit. Yesterday we have successfully booted up our board. But today, From morning onwards when we Switched it on, it is not getting booted. Showing CCCCCCCCC on console. We verified our DTS file & again we created SDCard and tried. We copied MLO, u-boot into boot partition and am33xx-evm.dtb, ZImage into rootfs partition many times. But we are unable to get anything except CCCCCCCC on the console. Can anybody tell me how to solve this?

If anybody has encountered with this problem earlier, please help me in this regard as I have a severe time restriction.

Thank You.

1. Is this a single board, or you see the same problem on multiple boards? Have you double-checked your SYSBOOT settings and power supplies?
2. Does your board have an ID EEPROM? If you don't have one, have you skipped the EEPROM check in MLO?
3. What is the Linux version you use?

1. It's a single board. We've checked our SYSBOOT settings. Please suggest us which power supplies i've to check?
2. No, there is no EEPROM. We've skipped it in our u-boot settings.
3. Our linux version is "ti-processor-sdk-linux-am335x-evm-05.00.00.15"

For the hardware check, follow this wiki: processors.wiki.ti.com/.../AM335x_board_bringup_tips
Also take a look at the SD card holder. It may have been damaged or unsoldered.
