For a flash chip I m using, the time to do a 64KB block erase is significantly faster than a whole series of sector erase commands. For 1MB, this is about 800ms vs 7500ms. I d be happy to send a PR to ...

I have some W25N01GV chips that I ve been playing with. These are still 25-series, but they re NAND flash and have a slightly different instruction set. This crate provides an excellent starting point ...

While waiting for the flash memory to complete its work, a lot of time can traverse. In my case I have a radio IC on the same SPI as the flash memory that logging is happening on, and it would be awesome ...

currently the sector size using in erase_sectors is implicit, this makes it hard to write generic code that uses the flash traits since it can t know how many sectors it needs to erase for a given write. ...

write_bytes does not appear to manage non-sector aligned memory accesses. This may not be a constraint on all devices, but is definitely the case for some To mitigate this writing 256-bytes at address ...

AFAIK, you can t use this with any other SPI peripherals on the same SPI. 2 solns: - Mutably borrow the spi periph - Allow it to be freed. I think the first is the better approach. Thoughts?

It was extremely difficult soldering a AT45DB021E to it since its footprint is much wider. The Dev-Board should accommodate for this by having footprints that work with as many chips as possible.

Currently there s only a Debug impl. Ideally we d also implement Error, but that doesn t exist in libcore, and I m not sure adding a std feature is worth it.

Currently RN1 is a 4x0603 10k resistor array, which is apparently not easy to get (I substituted discrete 0603 resistors because Digikey didn t have a fitting resistor array). It should be replaced by ...
