+CC Altera guys, they might help too.
Hmmm.... quite strange to write for sector aligned. Wonder the write related to filesystem access?
Within Cadence QSPI controller, read and write access need to be done within a page. But that would be taken care by controller when the access beyond the next page. From software perspective, we just tell controller the numbers of bytes to be transfer (for indirect transfer setup).
My needs have evolved a bit, and I no longer require this function. But I wasn't able to right a file tftp into RAM using 'sf update' without this patch. I could try to reproduce the errors and maybe dig in a little more.
This would be really helpful. Esp. since the Cadence QSPI driver is coming to mainline in next MW.
Thank you!
