Hi everyone,
we use the S25HL512T with QUAD-SPI interface and find some issue about QPI read.
some test pattern as follow:
[Test pattern]
Write 256 bytes Data
Data pattern1 : { 0x00, 0x01, 0x02 ... 0xFD, 0xFE, 0xFF }
Data pattern2 : { 0xFF, 0xFE, 0xFD ... 0x02, 0x01, 0x00 }
[Write Command]
0x02
[Read Command]
0xEB (SDR) or 0xED (DDR)
[Erase Command]
0x20
[Protocol]
QPI SDR or DDR
[Address Byte Length]
3 bytes or 4 bytes
When we read the 256-byte data, once read a byte is 0x0F or 0xF0, behind 0x0F or 0xF0 data became abnormal.
Does somebody encounter the same problem?
