Hi Bin,
I find that 'sf test 0 1000' does not work anymore since this commit:
c4e8862308 mtd: spi: Switch to new SPI NOR framework
Have you seen any problems? This seems to prevent proper SPI flash writing (not sure about reading).
Yes, this seems to be broken. I just tested it on MinnowMax.
What is the flash part on this board?
'sf probe' does not succeed anymore.
Could you enable all debug prints in spi_mem_exec_op() in spi-mem.c: https://elixir.bootlin.com/u-boot/latest/source/drivers/spi/spi-mem.c#L376
And the post the full log here. If the log is too big please paste it to pastebin.ubuntu.com
Also please apply http://patchwork.ozlabs.org/patch/1090121/ on top of latest tree before doing any write to flash
Sorry for the trouble.
Sorry for the long delay. I finally got time to look into this.
However with the latest u-boot/master, the SPI flash seems to work again on Intel MinnowMax. Did you recall anything changes in the spi-nor recently?
