I am running the P8 SPIFLASH version of Espruino by @fanoush on a similar smart watch, but I have managed to get the Flash memory into a strange state whereby I cannot write to it with the Storage class.
The Flash is writeable - I can update the bootloader and flash Espruino builds to it. I can also erase, read and write flash pages, but any attempt to write a file fails with a timeout. Rebooting doesn't help. This device has been working well, and I had been reading and writing to Storage, but it seems that something is out of alignment!
