Issues with SD card

[amirgon]

I've followed the wiki to attach an SD card.

When calling sdmmc_card_init slot=1, host=SDMMC_HOST_DEFAULT() I'm getting:

E (37117) sdmmc_req: sdmmc_host_wait_for_event returned 0x107
E (47247) sdmmc_req: sdmmc_host_wait_for_event returned 0x107

I've tried increasing host.command_timeout_ms up to 10000, didn't help.

Looking at the debugger, it looks like sdmmc_host_wait_for_event is waiting to some interrupt that is never recieved on s_event_queue.
On QEMU I can see non-implemented reads being sent. For example, sdmmc_io_reset sends a command that is received on the QEMU side by dwc_sdmmc_read with offset 80 but unhandled, I'm not sure whether it's related or not.

@amirgon does the version of esp-idf which you are using include commit espressif/esp-idf@6782971? If not, could you try cherry-picking it?

Yes! After cherry-picking this fix I no longer see this problem.
Thanks!

It could be nice, though, if QEMU generated a delayed CMD_DONE interrupt.
It would model the real hardware more accurately and, more importantly, be compatible with esp-idf versions older than v5.0.
