Hello ,everyone. I am developping a program on bf561which use both PPI0 and PPI1. DMA error happened everytime when writing to intel flash. I have checked that wring flash only cost 50 us . So why this happened? Does anyone has gotted same problem?
PS: It is an intel nand flash.
Error happened when it is reading flash status register , but not happened when it is reading flash content.
Sorry for the delay in response. Not sure if you have solved your problem or not --- if you have not, could you provide some more details, such as how you are talking to the flash and which peripheral you are using (EBIU, SPI, etc). Does the system fail when only one PPI is being used? How - or is - your system partitioned between cores?
