Hi Robert, After some "research" of the bug I came across this bug post in one of your github repositories: https://github.com/RobertCNelson/armv7-multiplatform/issues/25 . As you stated you worked some time trying to figure out the error and there you have the proof ;). After reading all the messages I encountered with the last one, which suggest applying this patch https://github.com/balena-os/balena-beaglebone/blob/master/layers/meta-balena-beaglebone/recipes-kernel/linux/linux-beagleboard-4.14/0001-card-power-cycle.patch . I tried it and ... it worked perfectly! Of course I'm unable to explain why it fixes it, but I thought that maybe we can show this to someone you might know or maybe get in touch with the guys from Balena, in order to have a proper fix mainline. I feel that this is a big issue for those using the BeagleBoard-xM and trying to use the latest releases. I tried 3 different microSD cards and neither of them worked with the latest releases. I will attach two dmesg: the first one corresponds to the kernel without the patch and second one with it. If you think that more information is needed or want me to perform some type of debugging, just tell me! I'm willing to help to solve this issue in the best possible way.
Again, and knowing that I'm repeating myself, thank you for taking the time with this topic, von Bergen, Federico Without patch: ``` U-Boot SPL 2018.03-00001-g21a26066ea (May 21 2018 - 15:23:05 -0500) Trying to boot from MMC1 spl_load_image_fat_os: error reading image args, err - -2 U-Boot 2018.03-00001-g21a26066ea (May 21 2018 - 15:23:05 -0500), Build: jenkins-github_Bootloader-Builder-49 OMAP3630/3730-GP ES1.2, CPU-OPP2, L3-200MHz, Max CPU Clock 1 GHz Model: TI OMAP3 BeagleBoard OMAP3 Beagle board + LPDDR/NAND I2C: ready DRAM: 512 MiB NAND: 0 MiB MMC: OMAP SD/MMC: 0 Loading Environment from NAND... *** Warning - readenv() failed, using default environment Failed (-5) Beagle xM Rev C No EEPROM on expansion board No EEPROM on expansion board OMAP die ID: 037600029ff8000001578ca00f01d013 Net: usb_ether Hit any key to stop autoboot: 0 switch to partitions #0, OK mmc0 is current device Scanning mmc 0:1... switch to partitions #0, OK mmc0 is current device SD/MMC found on device 0 Checking for: /uEnv.txt ...
