Patch applied, and now the eMMC is detected OK:
=> mmc info
Device:
Manufacturer ID: 15
OEM: 100
Name: BGND3
Tran Speed: 5200
Rd Block Len: 512
MMC version 5.0
High Capacity: Yes
Capacity: 29.1 GiB
Bus Width: 8-bit
Erase Group Size: 512 KiB
HC WP Group Size: 8 MiB
User Capacity: 29.1 GiB WRREL
Boot Capacity: 4 MiB ENH
RPMB Capacity: 4 MiB ENH
... And I can load/boot the Kernel (as far as the /dev/mmc... prompt..)
Thanks!

Yes, this is expected since the muxing in the board file is only enabling the SDcard. Could you try to set the correct muxing also for the eMMC and check again? Unfortunately I don't have an eMMC for the Odroid-C2 to check this out. I'll try to prepare a board file also for the P20x so I can test this better. Thank you for testing this BTW.

Applied this on my Odroid C2, and it worked OK when installed on the SDcard, but failed when installed on the eMMC module: => version U-Boot 2016.05-rc3 (May 14 2016 - 21:06:28 -0700) odroid-c2 aarch64-linux-gnu-gcc (GCC) 5.3.1 20160212 (Red Hat Cross 5.3.1-2) GNU ld version 2.26.20160125 => mmc info Card did not respond to voltage select!

[U-Boot] [PATCH 0/2] Add support for Amlogic Meson MMC controller
From: Carlo Caione This patchset is a port / rewrite of the Amlogic driver shipped in the SDK for the Meson GXBB (S905) platform. It has been tested on the Hardkernel Odroid-C2 board. The driver is enabled using U_BOOT_DEVICE in the board file because there is no MMC driver yet in the linux kernel. This patchset depends on the basic support for Amlogic S905 SoCs written by Beniamino[1] [1] https://www.mail-archive.com/[email protected]/msg212188.html Carlo Caione (2): mmc: Add Amlogic Meson driver arm: amlogic: Enable MMC driver on Odroid-C2 arch/arm/include/asm/arch-meson/sd_emmc.h | 109 +++ board/hardkernel/odroid-c2/odroid-c2.c| 42 configs/odroid-c2_defconfig | 5 + drivers/mmc/Makefile | 1 + drivers/mmc/meson_mmc.c | 305 ++ include/configs/odroid-c2.h | 7 + 6 files changed, 469 insertions(+) create mode 100644 arch/arm/include/asm/arch-meson/sd_emmc.h create mode 100644 drivers/mmc/meson_mmc.c -- 2.7.4 ___ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
