I was try to program and read the flash in MKW41Z512, when I program, I do mass erase first, and it could erase and program successful, but after that, I restart ( power off then power on) the sample, and do read operation, but it could not read successfully. If do mass erase first, it could read, but all of the value are oxff. The same code could run successfully in MKW31Z256VHT4, (not do mass erase, could read ok.)
Would you please help to check the problem?
Thank you very much!
