We are using BDI3000 to Burn u-boot.bin to Flash memory. The flash we are using is Spansion S29GL512S.
As per the flash datasheet we tried programming 4 bytes( using telnet mmb command) write buffer programming cycle. We succeeded. But when we tried programming a binary file ( u-boot.bin) ,it was failing. Even though the log shows Flash programming passed but in the location when we do a mdh there is no u-boot data. Please find the log captured below.
