Tool/software: TI-RTOS
Hi,
We have a CC2640R2F custom board with Adesto AT25XE041B external flash. I managed to integrate extFlash.h driver from simple_peripheral_cc2640r2_oad_offchip example, but the thing is, that we need to use SPIFFS and SPIFFS uses NVS.
To make extFlash driver work, I had to:
- change "Read Manufacturer and Device ID" pin from 0x90 to 0x9F,
- modify ExtFlash_readInfo() to send only one byte
- add AT25XE041B manfId (0x1F) and devId (0x44) to flashInfo
- implement ExtFlash_global_unprotect function, since this extflash seems to be write protected by default.
Now I should do similar thing with NVS, but I am bit lost.
Driver implementation seems to be in NVSSPI25X.h, but there is no "Read Manufacturer and Device ID" logic nor protect/unprotect logic.
Should I be able to make NVS work, without these somehow? Or how should I implement them?
