This is the problem I am currently experiencing:
I'm using a CYC3 which has :
- EP3C16Q240C8N
- M25P64 SPI FLASH for AS config device
- MSEL[2:0]=010
- QUARTUSII 8.0
in the "qsf" file define :
set_location_assignment PIN_24 -to data0_to_the_epcs_controller
set_location_assignment PIN_23 -to dclk_from_the_epcs_controller
set_location_assignment PIN_14 -to sce_from_the_epcs_controller
set_location_assignment PIN_12 -to sdo_from_the_epcs_controller
using uclinux(nioswiki)
change the config.c to:
#define EPCS_SPI_OFFSET 0x400 /* FIXME */
.
.
.
static struct flash_platform_data nios2_spi_flash_data = {
.name = "m25p80",
.parts = nios2_spi_flash_partitions,
.nr_parts = ARRAY_SIZE(nios2_spi_flash_partitions),
.type = "m25p64", /* depend on the actual size of spi flash */
};
and the other following the site :
http://www.nioswiki.com/mtd when I download to the board:
nios2-download -g zImage
nios2-terminal
the debug window display :
m25p80 spi0.0:found m25p80 expected m25p64
Am I missing something ?
thanks
