I have a BeagleBone Wireless with a damaged eMMC card. I got mmcutils from https://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc-utils.git, and mmc extcsd read /dev/mmcblk1 gives me this for the lifetime estimation: eMMC Life Time Estimation A [EXT_CSD_DEVICE_LIFE_TIME_EST_TYP_A]: 0x0b eMMC Life Time Estimation B [EXT_CSD_DEVICE_LIFE_TIME_EST_TYP_B]: 0x08 Not good, should be something like 0x01 (less that 10 percent), according to https://www.cnx-software.com/2019/08/16/wear-estimation-emmc-flash-memory/
Also, looking at the devices I do not see a mmcbl1p1. root@beaglebone:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT mmcblk0 179:0 0 14.9G 0 disk └─mmcblk0p1 179:1 0 3.5G 0 part / mmcblk1 179:8 0 3.6G 0 disk mmcblk1boot0 179:16 0 2M 1 disk mmcblk1boot1 179:24 0 2M 1 disk mmcblk1rpmb 179:32 0 512K 0 disk I am trying to boot the beaglebone from SD-card for the moment, until i get another one, but it will only boot when i use press the power and the boot button next to the sd-card. I tried to get rid of the boot flag on /dev/mmcblk1, as per instructions on https://www.erdahl.io/2016/12/beaglebone-black-booting-from-sd-by.html but I get errors getting to the eMMC: fdisk: cannot open /dev/mmcblk1: Input/output error Is there any way I can disable the eMMC somehow, so that it does not interfere with the booting of the sd-card and automatically boots the sd-card?
