Hi, working with the TI AM335x Evaluation Module I noticed that the function am335x_sdram_size() always returns 0 instead of the computed sdram size. I could trace back the problem to the fact that the function does its computation based on the value of the register CM_EMIF_SDRAM_CONFIG (addr. 0x44e10110), but this register is not written to by the function am33xx_config_sdram() and just returns its initial value (0). The datasheet says CM_EMIF_SDRAM_CONFIG should have the same value as AM33XX_EMIF4_0_REG(SDRAM_CONFIG) (addr. 0x4c000008) To conclude, to fix the problem with am335x_sdram_size() you can either use AM33XX_EMIF4_0_REG(SDRAM_CONFIG) instead of CM_EMIF_SDRAM_CONFIG in am335x_sdram_size() or initialize CM_EMIF_SDRAM_CONFIG in am33xx_config_sdram() with the same value as AM33XX_EMIF4_0_REG(SDRAM_CONFIG) (regs->sdram_config) giorgio _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
