Hi all,

I am trying to read SPI flash memory with SPIFI interface but it does not show proper data in memory.

SPIFI_INIT function returns successfully and it alos provies proper information for JEDEC ID.

But erase and program does not work, also document does not provide more information. Is any body have done it successfully?
Regards,
Lalit Shah

There are at least 3 spifi_init(), I know:
1) in the bootROM (report chip revision plz)
2) in the spifi_drv_M3.lib which is from AN11206.zip
see LCD_SPIFI/Drivers/lib/SPIFI_ROM_support.doc
3) in the spifi_drv_M3.lib which is from CMSIS 'lpc18xx-2012-12-11.zip'
see Drivers/lib/SPIFI_report v0.1.pdf

Which one do you use ?
Which document did you read ?

(AT25DF041A is pure 1bit SPI device ?)
