Question about C6657EVM NAND BOOT

Yifeng Xiong

Hi,

I configured the NAND BOOT according to the readme file of mcsdk provided by TI, and loaded the RS232 test program included by the mcsdk onto NAND FLASH. The serial port should return some version information upon success, while it actually keep printing "IBL: Booting from NAND" when I am testing the code. I noticed that if I "refresh memory", the memory content after 0x80000000 keeps changing after I loaded the program to 0x80000000. Is this a problem? What should I do about it?

Thanks,

Yifeng

Hi,

Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com).

Please run the platform test to ensure that external memory is working. Please find the platform test in below path.

PATH: ..ti\pdk_C6657_1_1_2_6\packages\ti\platform\evmc6657l\platform_test

Thanks.

Hi,
Would you able to run platfrom_test successfully?

Thank you.

Hi,

I am so sorry for the delay. The platform_test is passed, and the boot issue remains.

Looking forward to your further advice.

Thanks,

Yifeng

Hi,

Have you programmed the nand flash with application? If not, follow the instructions provided in the NAND writer utility.

Thanks.
