For DDR2 RAMs, regs->zq_config is not used, which causes the AM33XX_EMIF4_0_REG(SDRAM_CONFIG) register to be left unconfigured, resulting in boot failure. It seems that the DDR2 case was missed during the consolidation in commit 9f122f8bf023a12ad5f84b61d1d74d3ff06104dd. The actual call for the Bone was removed in 88659d9c4a87a730f6efe4f38c011e8e0214a67b. Signed-off-by: Jan Luebbe <jlu@xxxxxxxxxxxxxx> --- I've tested this on White and Black BeagleBones. An additional test on the PCM051 would be good. arch/arm/mach-omap/am33xx_generic.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/mach-omap/am33xx_generic.c b/arch/arm/mach-omap/am33xx_generic.c index 251c8d4..3e2b6c4 100644 --- a/arch/arm/mach-omap/am33xx_generic.c +++ b/arch/arm/mach-omap/am33xx_generic.c @@ -302,7 +302,7 @@ void am33xx_config_sdram(const struct am33xx_emif_regs *regs) writel(regs->sdram_ref_ctrl, AM33XX_EMIF4_0_REG(SDRAM_REF_CTRL)); writel(regs->sdram_ref_ctrl, AM33XX_EMIF4_0_REG(SDRAM_REF_CTRL_SHADOW)); - writel(regs->sdram_config, CM_EMIF_SDRAM_CONFIG); + writel(regs->sdram_config, AM33XX_EMIF4_0_REG(SDRAM_CONFIG)); } void am33xx_config_io_ctrl(int ioctrl) -- 1.7.10.4 _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
