How do you put the image into it to begin with? Don't tell me you were using an external tool or a hacked version of older U-Boot.
This patch enables data read above 16MB using AHB (on Uboot prompt) and does not involve our QSPI driver. It is equivalent to reading from DDR via
cp or md commands.
Whereas writing to flash is possible via IPS mode which involves our driver (using sf commands).
OK. So we are still far away to have the full flash supported.
AHB Write is not supported by QSPI hardware.
