Base commit: 7e6e40c57233 ("Merge tag 'v2023.10-rc3' into next") I can't get this to boot. Seems to be stuck in the r5 spl. Boot log is: U-Boot SPL 2023.10-rc3-01591-ga4f9ddf99438 (Aug 22 2023 - 17:11:47 +0200) SYSFW ABI: 3.1 (firmware rev 0x0009 '9.0.5--v09.00.05 (Kool Koala)') SPL initial stack usage: 13400 bytes Trying to boot from MMC1 mmc_load_image_raw_sector: mmc block read error Partition 1 invalid on device 0 spl_register_fat_device: fat register err - -1 spl_load_image_fat: error reading image tispl.bin, err - -1 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ### It seems that when we try to find tispl.bin, we read from the mmc0boot0 hw partition instead of from the user partition. Per my understanding, BeaglePlay has the following (simplified) boot flow: 1. boot rom loads tiboot3 from mmc0boot0 2. tiboot3 loads tispl.bin from mmc(user), first partition (on a FAT filesystem) 3. tispl loads u-boot.img from mmc(user), first partition (on a FAT filesystem) With the folllowing diff, I can boot all the way to U-Boot proper: diff --git a/board/ti/am62x/beagleplay_a53.config b/board/ti/am62x/beagleplay_a53.config index 4889e1bc6f2b..d59a3ca6926e 100644 --- a/board/ti/am62x/beagleplay_a53.config +++ b/board/ti/am62x/beagleplay_a53.config @@ -18,3 +18,8 @@ CONFIG_SPI=n CONFIG_SPI_FLASH=n CONFIG_SPL_DM_SPI_FLASH=n CONFIG_SPL_SPI_FLASH_SUPPORT=n + +CONFIG_SUPPORT_EMMC_BOOT=y +CONFIG_SUPPORT_EMMC_BOOT_OVERRIDE_PART_CONFIG=y +CONFIG_SYS_MMCSD_RAW_MODE_EMMC_BOOT_PARTITION=0 diff --git a/board/ti/am62x/beagleplay_r5.config b/board/ti/am62x/beagleplay_r5.config index ce64561bee92..239d0d6a55bd 100644 --- a/board/ti/am62x/beagleplay_r5.config +++ b/board/ti/am62x/beagleplay_r5.config @@ -9,3 +9,8 @@ CONFIG_SPI=n CONFIG_SPI_FLASH=n CONFIG_SPL_DM_SPI_FLASH=n CONFIG_SPL_SPI_FLASH_SUPPORT=n + +CONFIG_SUPPORT_EMMC_BOOT=y +CONFIG_SUPPORT_EMMC_BOOT_OVERRIDE_PART_CONFIG=y +CONFIG_SYS_MMCSD_RAW_MODE_EMMC_BOOT_PARTITION=0 The above is probably not the proper way of doing things, but it seems to resolve my booting issue. > > arch/arm/dts/Makefile | 2 + > .../dts/k3-am625-beagleplay-ddr4-1600MTs.dtsi | 2195 +++++++++++++++++ > arch/arm/dts/k3-am625-beagleplay-u-boot.dtsi | 172 ++ > arch/arm/dts/k3-am625-beagleplay.dts | 758 ++++++ > arch/arm/dts/k3-am625-r5-beagleplay.dts | 87 + > arch/arm/dts/k3-am625-sk-binman.dtsi | 4 +- > board/ti/am62x/MAINTAINERS | 7 + > board/ti/am62x/beagleplay_a53.config | 20 + > board/ti/am62x/beagleplay_r5.config | 11 + > doc/board/ti/am62x_beagleplay.rst | 121 + > doc/board/ti/k3.rst | 1 + > 11 files changed, 3376 insertions(+), 2 deletions(-) > create mode 100644 arch/arm/dts/k3-am625-beagleplay-ddr4-1600MTs.dtsi > create mode 100644 arch/arm/dts/k3-am625-beagleplay-u-boot.dtsi > create mode 100644 arch/arm/dts/k3-am625-beagleplay.dts > create mode 100644 arch/arm/dts/k3-am625-r5-beagleplay.dts > create mode 100644 board/ti/am62x/beagleplay_a53.config > create mode 100644 board/ti/am62x/beagleplay_r5.config > create mode 100644 doc/board/ti/am62x_beagleplay.rst > > -- > 2.40.0
