Hello,

I'd like to boot my sorio from SDcard instead of the internal eMMC. Here are some outputs I got:

Storio 3 without eMMC and without SDCARD:

Code:
iROM v3 Entry A400-S160 MHz



SPI Boot...(ID: 0x00) Fail

Nand Boot...NF_NON_SHARE->Fail

SDC/eMMC Boot...cmd SD_STATUS = 0x304

cmd SD_STATUS = 0x304

cmd SD_STATUS = 0x1304

Fail

cmd SD_STATUS = 0x304

cmd SD_STATUS = 0x304

cmd SD_STATUS = 0x1304

usb_reset()

usb_initial()

USB/ICE Service Entry

With a prepared SDcard I receive this:

Code:
iROM v3 Entry A400-S160 MHz



SPI Boot...(ID: 0x00) Fail

Nand Boot...NF_NON_SHARE->Fail

SDC/eMMC Boot...cmd SD_STATUS = 0x304

cmd SD_STATUS = 0x304

cmd SD_STATUS = 0x1304

Fail
