it's too bad the new framework doesnt allow for dynamic probing like the spi layer. makes it a pain to work with a SPI/MMC card that can have the CS changed on the fly.
Second thought. With generic mmc framework, we can instance multiple mmc devices. Then we can probe one of them when we want.
i dont think that's a scalable solution. what if you have multiple spi busses or 10's of GPIO CS's ? only way to scale is to have a new subcommand so people can do it themselves. a simple CONFIG_CMD_MMC_SPI command which forwards along calls to mmc_spi_init() on the fly would work. -mike
Hi Mike,
I have resolved the SDHC issue and have tested various MMC/SD cards, including writing. I will submit the patch tomorrow.
I have moved spi slave setup so that we can change the cs on the fly. We could add a subcommand, like,
mmc_spi [bus:]cs
Where should I place this command? in a new file in common dir or inside the mmc_spi driver?
Cheers, Thomas
