This PR has been updated to use a new, but unreleased version of `block-device-driver` which includes buffer alignments within the trait itself https://github.com/MabezDev/embedded-fatfs/pull/23. Release of the new version is blocked...

Feel free to submit a PR to enable the register for your chip during SDMMC initialization :)

Transactions should build on top of the existing read/write implementations, so this should be straight forward to implement.

> How do you guys handle this in no_std? We implement both where possible, but I don't think its a super strict rule. For example, we don't implement any of...

So the [CONFIG_RMT_ISR_IRAM_SAFE](https://docs.espressif.com/projects/esp-idf/en/v5.1/esp32/api-reference/kconfig.html#config-rmt-isr-iram-safe) config option will handle the C side of putting the required methods in IRAM, so we then just have to worry about the rust side when we...

The copying code will be buried deep in the startup code for esp-idf, but provided we also put our Rust functions there, i.e by using `#[link_section = ".iram1"]` then it...

Maybe related to https://github.com/esp-rs/rust/issues/176? What happens if you build esp-idf with clang, instead of GCC?

I have seen this too, to reproduce my case: 1) Manually put the chip into download mode, hold boot whilst resetting the chip 2) flash it with espflash 3) Observe...
