Determine SPI flash size
Posted: Fri Sep 25, 2015 6:57 amHi
I have a number of ESP-201 and 01/07/12/12E modules, a lot of which have the metal can over the ESP8266 and the SPI flash chip.
For some of them, I can identify the flash chip from it's manufacturer ID and device ID. For some, the ID isn't a familiar one.
Is there a list of device IDs and corresponding sizes anywhere?
(Of course, I could either flash a custom firmware which does a similar thing to NodeMCU's node.info(), and retrieves the flash size by reading at successive boundaries until it fails, which I am currently doing)
