#162711 - A common mistake... Responding to: ???'s previous message |
Sarma:
Are you by chance trying to do some large block size read test that is proceeded with a write block of the same size? If so do note that write block commands to this part are limited to size of no more than 128 bytes. If you attempt to write a block that crosses a page boundary of 2^^7 (128 byte physical address boundary) the latter data is loaded into the beginning part of the same page and _not_ the beginning of the next page. If you did not comprehend this then the write test pattern would not be the same as you would expect from the read block. Michael Karas |
