Should be easy to do. Change the boot configuration so that you don't try to boot from mmc1.

Here a handy chunk of schematic to help with that. https://e2e.ti.com/support/processors/f/791/t/661109?AM3358-SYSBOOT-configuration J On Mon, Nov 25, 2019, 10:16 PM Johan Henselmans <[email protected]> wrote: > > 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? > > Kind Regards, > Johan Henselmans > > -- > For more options, visit http://beagleboard.org/discuss > --- > You received this message because you are subscribed to the Google Groups > "BeagleBoard" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion on the web visit > https://groups.google.com/d/msgid/beagleboard/42459d9f-02f0-494c-b0d7-f2778098dae0%40googlegroups.com > <https://groups.google.com/d/msgid/beagleboard/42459d9f-02f0-494c-b0d7-f2778098dae0%40googlegroups.com?utm_medium=email&utm_source=footer> > . > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
