Ivan Grokhotkov	c6829fa5b8	sdmmc: improve error handling during SPI mode init ... - In SPI mode, the card will respond to the initial SDIO reset (done using CMD52) with “invalid command” error. Handle this correctly. - sdmmc_card_init had a hack where GO_IDLE_STATE (CMD0) command was sent twice. Add explanation why this is done, and don’t expect correct response from the card on first CMD0. - improve logs printed at debug level by adding CMD index	2018-04-11 11:11:17 +08:00
Ivan Grokhotkov	269486ca4d	sdspi: use response timeout passed from upper layer ... Previously SDSPI host driver would rely on retry count when waiting for the card to read or write data. This caused different timeout times depending on CPU frequency and card clock frequency. In practice, card performance does not depend on these two factors. This change uses timeout_ms field of sdmmc_command_t introduced previously for SDMMC host. Fixes https://esp32.com/viewtopic.php?f=2&t=3440&p=16037 and similar issues related to SDSPI timeouts.	2017-12-11 11:07:08 +08:00
