We are using an Alliance AS5F34G04SND-08LIN NAND flash chip on a custom board with a STM32F469 MCU. I have emFile working correctly with it so all is good there. Because the Alliance AS5F34G04SND-08LIN does not support ONFI emFile is not able to detect the NAND specs on the chip. So I was forced to define my device config structures within FS_NAND_PHY_SPI.c. That works, but now my code is within the emFile source, rather than defined in my project files. I looked at what it would take to define …
