Hi, all!
I'm new to the forum and, keeping with the long time tradition, my first message is asking for help and guidance :D I'm developing my own board based on the Allwinner V3S SOC. For most of the hardware I've followed the schematic for the Lichee Pi Zero. After struggling with the power supply, I finally (believe) that I got the timings right and the voltages stable. Now I'm trying to understand the U-Boot boot process to see why I'm stuck on getting the board booting. Long story short: U-Boots stops after it outputs the DRAM amount. The first thing I did was trying to check the stability of the CPU. For that, I've injected a code right before the "Trying to boot from" message, with an infinite loop, doing arithmetical calculations and outputting to UART. I left this code running overnight and it kept running fine. Alright, so I assume my CPU is stable... so moving forward... Any U-Boot code wizards out there that could give me a hand on identifying exactly where it is stuck, so I could give me a clue if it's hardware or firmware related? Bellow is my latest log. - It has verbose 9 level enable everywhere plus CONFIG_TRACE enabled. - The [number] before the "DRAM" lines was injected by me to try locating the code line that was outputting it. - the message "board_init_f finished" I inserted at the last line of the board_init_f function. Thanks a bunch! -------------------------------- U-Boot SPL 2024.04-rc4 (Mar 22 2024 - 18:31:19 -0300) [5]DRAM: 64 MiB size=18, ptr=18, limit=100000: 4fd00000 Trying to boot from MMC1 common/malloc_simple.c:27-alloc_simple() size=190, ptr=1a8, limit=100000: common/malloc_simple.c:48-malloc_simple() 4fd00018 drivers/mmc/mmc.c:196-mmc_select_mode() selecting mode MMC legacy (freq : 0 MHz) drivers/mmc/mmc.c:196-mmc_select_mode() selecting mode MMC legacy (freq : 25 MHz) drivers/mmc/mmc.c:1821-sd_select_mode_and_width() trying mode SD High Speed (50MHz) width 4 (at 50 MHz) drivers/mmc/mmc.c:196-mmc_select_mode() selecting mode MMC legacy (freq : 25 MHz) drivers/mmc/mmc.c:1821-sd_select_mode_and_width() trying mode SD High Speed (50MHz) width 1 (at 50 MHz) drivers/mmc/mmc.c:196-mmc_select_mode() selecting mode SD High Speed (50MHz) (freq : 50 MHz) ers/core/lists.c:201- lists_bind_fdt() bind node leds drivers/core/lists.c:222- lists_bind_fdt() -
