Hi!
IIRC, then the aliases in the dts are very important for this:
aliases { spi0 = "/spi@ff705000"; /* QSPI */ ...
Did you add those to your dts as well?
I was using socrates dts for the moment, to keep diffs small. Suddenly it started working.. and stopped working after reset. Now I realized what is going on:
=> sf probe Invalid chip select 0:0 (err=-19) SF: Failed to set up slave Failed to initialize SPI flash at 0:0 => sf probe 0 0 0 Invalid chip select 0:0 (err=-19) SF: Failed to set up slave Failed to initialize SPI flash at 0:0 => sspi QSPI: Error, command is empty. Error -1 during SPI transaction => sf probe 0 0 0 raise: Signal # 8 caught raise: Signal # 8 caught raise: Signal # 8 caught SF: Detected N25Q512 with page size 256 Bytes, erase size 4 KiB, total 64 MiB SF: Warning - Only lower 16MiB accessible, Full access #define CONFIG_SPI_FLASH_BAR =>
(u-boot 2015.04 final)
Is there missing initialization somewhere...?
