Hi, I am testing this new unified sunxi DRAM initialization on my Mangopi MQ board (Allwinner D1s) and can't get it working. I'm on S. Holland's u-boot branch d1-wip. I created a config for the board and modified dram_sun20i_d1.c with values Andre suggested here:
" According to the dump of some MangoPi MQ-1 firmware, the D1s should work with: CONFIG_SUNXI_DRAM_DDR2=y CONFIG_DRAM_CLK=528 CONFIG_DRAM_ZQ=8092665 CONFIG_DRAM_SUNXI_ODT_EN=0 CONFIG_DRAM_SUNXI_TPR0=0x00471992 CONFIG_DRAM_SUNXI_TPR11=0x30010 CONFIG_DRAM_SUNXI_TPR12=0x35 CONFIG_DRAM_SUNXI_TPR13=0x34000000 " Boot fails like this: U-Boot SPL 2024.01-rc1 (Jul 11 2024 - 06:29:02 +0300) sunxi_ram_probe: dram-controller@3102000: probing DRAM BOOT DRIVE INFO: V0.24 DRAM CLK = 528 MHz DRAM Type = 2 (2:DDR2,3:DDR3) DRAMC read ODT off ZQ value = 0x30 DDR efuse: 0xa DX0 state: 3 DX1 state: 0 ERROR: auto scan dram rank & width failed auto_scan_dram_config() FAILED DRAM init failed spl_board_init_f() failed: -19 resetting ... reset not supported yet ### ERROR ### Please RESET the board ### Am I the only one who is facing such problem? :) When I'm switching to this old asm based init code then the DRAM init works. br, Indrek
