Hello everyone,
I' have a problem about sd card(SPI mode) on u-boot (ver. u-boot-2011.12). when I use the 'fatls' command, I could not get the correct/expected result. EX: ========================================== (expect) ==> fatls mmc_spi 0 1694152 vmlinux_bin 877709 zimage 859412 zimage_bin 859476 uimage_bin 4 file(s), 0 dir(s) (Real world...:eek:) ==> fatls mmc_spi 0 1694152 vmlinux_bin 877709 zimage -1 zimage_bin / / / / 3 file(s), 4 dir(s) ========================================== But the SD device works well on uClinux (I try the 'ls', 'cat' on uClinux) Any ideas? I tried this on Altera DE-0 SPI core configs in SOPC are http://imageshack.us/photo/my-images/442/spicore.jpg (My system clk is 50MHz) The system info: http://imageshack.us/photo/my-images/198/de0basesystem.jpg I create my_fpag.h by "sopc-create-config-files (http://sopc.et.ntust.edu.tw/?p=toolchain-build.git;a=blob_plain;f=tools/sopc-create-config-files;hb=head)" script.
