Honored ContributorFlash memory problem
Hello, is it true that I cannot write 1MB of data into flash memory (4M)? I am using Altera DE2 Board. My code is as follow: --- Quote Start --- # include <stdio.h># include <stdlib.h...

Honored ContributorYes, when I transfer 65536 (64K) of data, it works fine. the result is as followed for 64KB: (the last 3 results)
--- Quote Start --- Value at 140FFF4 is 16381, written is 16381 Value at 140FFF8 is 16382, written is 16382 Value at 140FFFC is 16383, written is 16383 --- Quote End --- my flash base is 0x1400000. the last data was written into 0x140FFFC as shown above. now i set the size to be 131072 (128K). the output is: --- Quote Start --- Error writing into flash: -5 --- Quote End --- --- Quote Start --- So, I understand that now the first 64kb write at offset=0 is ok while the second write at offset=0x10000 fails. Is this right? --- Quote End --- Yes, at second write at offset 0x10000 fails.
