Hi, just playing around, and noticed getChipVer() returns 0xff (not 0x43 or 0x42 as the Readme says it should) Everything else works great (can read files, create files, browse directorys, etc - comms all working with the chip, just that one function that returns an odd result.

Hi Peter. That sounds interesting. Which board you are using? Which communication port, SPI or Serial? Speed setting for selected port?

petervanderwalt commented 2 years ago

Custom board (Been in production for about a year now, couple thousand happy units shipped out)
Over SPI (ESP32)
SPI set to default, not adding the spiSpeed parameter Ch376msc flashDrive(USB_CS, USB_INT); // chipSelect

Everything else works great so its not basic comms this time (:

It’s pretty awesome that you find it useful. Some kind of logger device? Logic analyzer would be useful to examine whats going on.
