about using spi mode sdcard bootup problem #175

Closed SanadaShinken closed 3 years ago

SanadaShinken commented 3 years ago

Hi, All:

After some tests, booting from spi mode sdcard still failed. the following is what i done for sdcard boot tests.

  1. create a fat16 partition on sd card. what I use is a Sandisk 32GB sd card. there is only one partition in the sd card.
  2. copy images/* file into fat16 partition.
  3. turn on fpga board, and wait the prompt shows boot from sd card failed.
  4. after into prompt, using spisdcardboot to boot up, it shows the same error.

where am I doing wrong??

Many thanks.

BR, Sanada

Hi @SanadaShinken,

can you provide the log of the boot and the list of files copied to the SDCard? Do you also have another SDCard you could test with? Also is it with an already supported board or a board you are adding support to?

Hi @enjoy-digital :

the boot log will provide after I test in my office. the board which I used to test is qmtech wukong board. the SD is 32GB, and the used files is extracted from https://github.com/litex-hub/linux-on-litex-vexriscv/issues/164. there are Image, rootfs.cpio, rv32.dtb, opensbi.bin, image.json.

@enjoy-digital :

the below message is the sd card boot log. if you need more message, please tell how to provide. Many Thanks.

@SanadaShinken: I did some cleanups/changes while merging the qmtech_wukong board support in LiteX-Boards. I directly reused the sdcard_pmod_io function from the Arty: https://github.com/litex-hub/litex-boards/blob/master/litex_boards/platforms/qmtech_wukong.py#L138. Could you do another test on your hardware with this updated code?

@enjoy-digital :

Thanks very much. I'll do the test as soon as possible. the test result will be upload in this issue.

@enjoy-digital :

Thank you very much!! the SDCard boot is working!!!

after some bios code tracing, comparison, try and error, the root cause is the spi clock setting. the clock of wukong board's spi sdcard is about 2MHz. when the clock setting is right, sdcard boot is work. Thank you very much.

BTW, I upload the latest setting of my current used. qmtech_wukong.platforms.txt qmtech_wukong.targets.txt
