Hello All. I found that automounting does not work without a GPT table. In the example below, it is not possible to automatically mount a partition from an MMC card. However, if I add the full paths to the command manually, everything works. barebox 2025.02.0-00690-ga6a0a0ba4f61 #12 Thu Feb 27 08:27:56 MSK 2025 Board: Mega-Milas MM-SM-SAMA5D2 AT91: Detected soc type: sama5d2 AT91: Detected soc subtype: sama5d27c_d1g ... sdhci-at91 b0000000.sdio-host@xxxxxxxxxxx: registered as mmc1 mmc1: detected SD card version 2.0 mmc1: registered mmc1 ... barebox@Mega-Milas Informer SAMA5D2:/ ls /mnt/mmc1.0 mount: Device or resource busy running automount command 'mount mmc1.0' failed ls: No such device barebox@Mega-Milas Informer SAMA5D2:/ automount -l /mnt/mmc1 mount mmc1 /mnt/mmc1.0 mount mmc1.0 /mnt/mmc1.1 mount mmc1.1 /mnt/tftp ifup -a1 && mount -t tftp $global.net.server /mnt/tftp /mnt/nfs ifup -a1 && mount -t nfs ${global.net.server}:/home/${global.user}/nfsroot/${global.hostname} /mnt/nfs /mnt/ratp mount -t ratpfs none /mnt/ratp barebox@Mega-Milas Informer SAMA5D2:/ automount /mnt/mmc1.0 "mount /dev/mmc1.0 /mnt/mmc1.0" barebox@Mega-Milas Informer SAMA5D2:/ ls /mnt/mmc1.0 BOOT.BIN barebox.bin barebox.env rootfs.squashfs With the GPT table on the MMC, everything works OK out of the box: sdhci-at91 b0000000.sdio-host@xxxxxxxxxxx: registered as mmc1 mmc1: detected SD card version 2.0 WARNING: mmc1: GPT:Primary header thinks Alt. header is not at the end of the disk.
