In my application I've to read single bytes from Flash.
spi_flash_read returns an error if len is set to 1
Is there a better way than reading 4 bytes and masking one of them ?

We will fix this limitation of spi_flash_* APIs at some point after 1.0. But internally this will be implemented as a four-byte read which discards unneeded bytes. I don't know of any way to do this without reading at least 4 bytes from flash.

Thanks a lot for this information.
At least this answer makes me feel better, since the fault is not between my ears
