![]() Hence, I can be sure that there are no issues in the creation of partitions. Note: The commands fdisk -l -u and mmc part (from u-boot console) list the new partitions properly on the eMMC. Any pointers to what might be going wrong would be very helpful. However, the above segmentation fault message is way too minimal to guess anything for me. The following is the output of the mkfs.ext4 operation: mk2efs 1.45.6 (2)įs_types for nf resolution: 'ext4'īefore partitioning and formatting, the eMMC already had some data and a partition table, hence I am not using the -E nodiscard option as I need to get rid of the old blocks. When it comes to the performance factor, you need to test them on the native OS because their performance is high on the respective operating systems. The command above throws a segmentation fault after successfully discarding the blocks in the first partition. Ext4 is the default file format used by the Linux operating system, whereas NTFS is the file system of Windows. ![]() However, after successfully partitioning the eMMC, I am unable to create an ext4 filesystem on any of the created partitions. I need to partition, format and flash certain contents from the SD Card onto the eMMC.įor my use case, I intend to perform these manipulations from an intramfs environment using shell scripts triggered by init, and reboot the system into the flashed RFS after the above eMMC modification. My imx8mm-var-dart board has two storage devices - SD Card and eMMC. I am working with Linux Kernel 4.19.35 for Arm64.
