I followed the steps to burn the image to the MMC and enter the following command: mkfs.ext4 / dev / mmcblk1 The system indicates the following error: mke2fs 1.44.5 (15-Dec-2018) Found a back partition table in / dev / mmcblk1 Proceed anyway? (y, N) y / dev / mmcblk1 is apparently in use by the system; will not make a filesystem here! I tried to burn the image on a USB: done the following order: sudo fdisk -l I can see that I have 2 partitions on the USB, I attach image, and select the sda1 partition I do the installation command, but from USB: mkfs.ext4 / dev / sda1 I see the following: mke2fs 1.44.5 (15-Dec-2018) Found a gpt partition table in / dev / sda Proceed anyway? (y, N) y Creating filesystem with 3942400 4k blocks and 987360 inodes Filesystem UUID: 724e6e48-df01-47d2-9cfc-fb28e3d86175 Superbloack blackups stores on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 1605632, 2654208 Allocating group tables: done Writing inode tables: done Creating journal (16384 blocks): done Writing supoerblocks and filesystem accounting information: done and all remains the same, there has been no sign of recovery What am I doing wrong or how can I fix the IOT2050?

To erase the eMMc with mkfs.ext /dev/mmcblk1 you need to run the Example Image from SD card or USB drive. The command is not for setting the image to its default state - it is to completely erase and format the disk. After doing this you need to write the image again to the respective drive. Best regards!

I have the USB inserted in the IO2050 with the example image recorded. The capture shows the boot priority and as eMMC is the last and I can not boot with USB I don't understand why I don't rip the image recorded with Win32 Disk Image. If you have any ideas it would be very helpful. thank you so much, Edu Attachment 1.jpg (486 Downloads)

At the end, the screen shows me inserting the password of the Linux user who has booted into the eMMC. Let's see if you're lucky and you can see something.

Seems the USB drive is either skipped because no bootable image is found or booting was not possible. I have seen some USB drives being too slow to respond and then being skipped. You said you have written the Example Image with Win32DiskImager to that USB drive? Can you try another USB drive or a SD card? Best regards!

Thank you very much. I have continued with the installation of the new image, V1.1.1, in the eMMC, as indicated in the document: Install_image_eMMc_V1.0.pdf and everything is correct. It has booted the new version for internal memory, without SD or USB, and the little I've tried from this version, I see things that have improved. I am very grateful. Edu
