Hi, I am using an Ubuntu image for the BBB rev c and am using this tutorial for manually putting together the SD card image rather than using the pre-made flasher image ( which is flashed onto the eMMC). This is because I tweaked the U-boot so that the environment is maintained in the eMMC rather than on an EXT4 file. In order to do that, I just hard coded the variables that would have been set by uEnv.txt into the default environment for testing purposes. Specifically, the following vars: -uname_r= <my_kernel_version> -enable_uboot_overlays=1 -uboot_overlay_pru=/lib/firmware/AM335X-PRU-UIO-00A0.dtbo
After getting it to boot successfully from my SD card, I noticed that when running 'lsblk' I do not see the eMMC's partitions that I eventually want to write my environment to. This is what I see: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT mmcblk0 179:0 0 29.7G 0 disk └─mmcblk0p1 179:1 0 29.7G 0 part / Why is it that I can't view mmcblk1 (the eMMC) as well as mmcblk1boot0 and mmcblk1boot1? Is it something that needs to be updated in fstab? I used an Ubuntu flasher image on the eMMC and when I boot from there, I am able to see both the SD card and the eMMC: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT mmcblk0 179:0 0 29.7G 0 disk └─mmcblk0p1 179:1 0 29.7G 0 part mmcblk1 179:8 0 3.6G 0 disk └─mmcblk1p1 179:9 0 3.6G 0 part / mmcblk1boot0 179:16 0 2M 1 disk mmcblk1boot1 179:24 0 2M 1 disk but when I boot from SD I cant see the eMMC. I did not disable the eMMC overlay as it shows in the serial debug that it got loaded in. Not sure what I can do about this. Thanks in Advance. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
