I have encountered the same problem. Have you made any new discoveries?
No. I think I need to use a different loader.
this problem was solved by increasing attempts to initialize MMC
changed sdmmc_init in file sdmmc.c as below
int sdmmc_init(sdmmc_pdata_t *data, sdhci_t *hci) {
data->hci = hci;
data->online = FALSE;
int retries = 10;
do {
if (sdmmc_detect(data->hci, &data->card) == TRUE) {
info("SHMC: %s card detected\r\n", data->card.version & SD_VERSION_SD ? "SD" : "MMC");
return 0;
}
mdelay(100);
} while (retries--);
return -1;
}
@olegk0 feel free to open a PR so we can merge this improvement 😄
Good afternoon. I constantly face such a problem: [I] AWBoot r6160 starting... [I] SMHC: sdhci0 controller v50310 initialized [W] SMHC: error 0x100 status 0x0 [W] SMHC: cmd timeout [W] SMHC: error 0x100 status 0x0 [W] SMHC: cmd timeout [W] SMHC: init failed, trying SPI A successful launch from SD occurs from 3~6 attempts. I have tried different SD. I have tried different boards(T113-S3). There is such a mistake everywhere. Tell me what could be the problem?
