I tested on the 1c20 this evening as well ... works fine. I will test on the 2c35 board tomorrow. I'd like to get a positive confirmation WRT the 1S10 and 1S40 before applying this patch.
Great! Please also check epcs/spi flash on EP1C20.
1. apply this patch, [PATCH] spi_flash: support old STMicro parts with RES
2. add the following to board/altera/nios2-generic/custom_fpga.h
/* epcs_controller.epcs_control_port is a altera_avalon_epcs_flash_controller */ #define CONFIG_SYS_SPI_BASE 0x82100200 #define CONFIG_ALTERA_SPI #define CONFIG_CMD_SPI #define CONFIG_CMD_SF #define CONFIG_SF_DEFAULT_SPEED 30000000 #define CONFIG_SPI_FLASH #define CONFIG_SPI_FLASH_STMICRO
3. sf probe 0 sf read/write
I'll apply the generic board patch to the nios 'next' branch, but I'd like to hold off on blowing away those other board trees until we get a chance to test the generic board on the actual targets. Fair enough?
OK.
