Hello Again, I have been working with UBoot but now when I try to boot my Linux kernel image that's inside my eMMC it displays the following: => boot CMD_SEND:0 ARG 0x00000000 RET -110 mmc_init: -110, time 10 ** Bad device mmc 1 ** CMD_SEND:0 ARG 0x00000000 RET -110 mmc_init: -110, time 11 ** Bad device mmc 1 **
I know it is a timeout error and I also know that the error occurs inside mmc-uclass line 31. I'm aware send_cmd() is defined in mmc.h but I honestly don't know how to dig deeper into this error.
mmc info works fine. Here's the mmc rescan log if it makes any use: => mmc rescan CMD_SEND:0 ARG 0x00000000 MMC_RSP_NONE CMD_SEND:8 ARG 0x000001AA RET -110 CMD_SEND:55 ARG 0x00000000 RET -110 CMD_SEND:0 ARG 0x00000000 MMC_RSP_NONE CMD_SEND:1 ARG 0x00000000 MMC_RSP_R3,4 0x00FF8080 CMD_SEND:1 ARG 0x40360080 MMC_RSP_R3,4 0xC0FF8080 CMD_SEND:2 ARG 0x00000000 MMC_RSP_R2 0xEB010D65 0x4D4D4320 0x205000AC 0x008E7300

Any guidance would be appreciated.
Please check if there is a pin conflict to configure, or if the mmc sequential number is correct.
On sama5d2 Xplained board, the eMMC works with the commands,
=> mmc info Device: sdio-host@a0000000 Manufacturer ID: fe OEM: 14e Name: MMC04 Tran Speed: 52000000 Rd Block Len: 512 MMC version 4.4.1 High Capacity: Yes Capacity: 3.7 GiB Bus Width: 4-bit Erase Group Size: 512 KiB HC WP Group Size: 4 MiB User Capacity: 3.7 GiB Boot Capacity: 1 MiB ENH RPMB Capacity: 128 KiB ENH
Thank you.

Forget it guys, I just realized what was wrong. reg = <0xf8038200 0x200>; Before it was reg = <0xf8038200 0x100>; So if anyone else (that wants to use the flexcom uart) asks you about this now there's another thing you can point to. If I encounter another problem or something I'll get back to you.
