I met a problem in using FM25V10 in my system. The controller is LPC1778 and the freqency is 20MHz, power sppuly: 3.3V, SPI mode 3(1,1)。 When I write or read data less then 512 bytes one time, there is no error for several years. But recently, I try to write or read data for 5856 bytes one time, there ofen take error, I read the errored data there are all 0xFF. I read the datasheet of FM25V10. The sets are all right. I doubt the freqency is too high, but the max is 40MHz and I was set 20MHz.
Solved! Go to Solution.

One of the possible reason is with the program in the controller LPC1778, like it does not assign enough buffer to transmit larger size data.
