I just ported U-Boot to another customer board. I noticed QSPI has problems and USB can be flaky. That's the standard cache issue we have, disabling dcache fixed that.
I am starting to wonder whether we're hitting some corner case here. Maybe we should eventually try and trace all the register reads and writes generated by the DDR calibration code both in old and new SPL and make a diff to see if something really did change.
Dinh, can you share the marking on the SoC and the DRAMs on your board?
My SoC is:
5CSEMA4U23C6N CACAU1525A
DRAMs are:
ISSI 1510 IS43TR16256A 15HBL K080 P4482100QER2 TWN
Thanks, that's indeed rev. C . About time I bang my head against the desk because this is creepy.
FYI
I've just spend some time trying to update the spl / uboot / kernel & rootfs image on our Altera socdk to use for some software testing / development. Unfortunately it fails in the mem calibration process with the latest uboot most of the time. And when it does boot somtimes fails loading uboot fomr the mmc.
Try this u-boot-socfpga/ddr branch [1] , see if it works for you.
[1] http://git.denx.de/?p=u-boot/u-boot-socfpga.git;a=shortlog;h=refs/heads/ddr
I downloaded a "snapshot" from the above link producing, u-boot-socfpga-1931be2.tar.gz
When I try to build for sockit or de0_nano_soc I get:
CC drivers/mmc/mmc-uclass.o CC drivers/mmc/dw_mmc.o CC drivers/mmc/mmc.o CC drivers/mmc/socfpga_dw_mmc.o drivers/mmc/socfpga_dw_mmc.c:9:28: fatal error: asm/arch/dwmmc.h: No such file or directory #include <asm/arch/dwmmc.h> ^ compilation terminated. make[1]: *** [drivers/mmc/socfpga_dw_mmc.o] Error 1 make: *** [drivers/mmc] Error 2
Thanks for spotting this. Did you try the most basic of basic approaches:
diff --git a/drivers/mmc/socfpga_dw_mmc.c b/drivers/mmc/socfpga_dw_mmc.c index 43a7e7e..097db81 100644 --- a/drivers/mmc/socfpga_dw_mmc.c +++ b/drivers/mmc/socfpga_dw_mmc.c @@ -6,7 +6,6 @@
#include <common.h> #include <asm/arch/clock_manager.h> -#include <asm/arch/dwmmc.h> #include <asm/arch/system_manager.h> #include <dm.h> #include <dwmmc.h>
The git tree is updated now.
