    As a result it is necessary to create the mbr partition? And why then the loader tries to look for the gpt partition? For example: GPT 0x3190d20 signature is wrong LoadTrust Addr:0x4000 Or nobody just knows what occurs in a blob from Rockchip?

    Help to understand with boot process. I watch documentation from rockchip. There it is specified that several gpt partitions have to be created. I take a sd-card with the image of the armbian which is written down on it. I start the gdisk. I receive result: GPT fdisk (gdisk) version 1.0.1 Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: not present *************************************************************** Found invalid GPT and valid MBR; converting MBR to GPT format in memory. *************************************************************** Disk /dev/sdd: 31176704 sectors, 14.9 GiB Logical sector size: 512 bytes Disk identifier (GUID): 1239DBE7-E7AC-4D30-B146-AEF177251577 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 31176670 Partitions will be aligned on 2048-sector boundaries Total free space is 344477 sectors (168.2 MiB) Number Start (sector) End (sector) Size Code Name 1 32768 30864927 14.7 GiB 8300 Linux filesystem Why so? It is really necessary to create the mbr partition?

    Hi all. Tell me please. How to get a uinitrd from a initrd.img?
  4. Hi. Why is the 2d drawing in X11 so slow? If you use mali blobs, the scrolling in the Windows is delayed, moving the Windows is done with jerks. Even when display compositing is enabled, you can see how the under level Windows are redrawn in parts. If you do not use mali blobs, the scrolling in the Windows is excellent. But the Windows move slowly. When the compositing is disabled, the window can reach several (5-7) seconds. One would think that the graphics accelerator and processor are slow. But I have experience using weaker devices (e.g. tegra k1 or exynos with mali t6xx). There such delays are not observed even in the mode without hardware acceleration.

    In WIKI the supply voltage is not specified. I had doubts.

    Sorry, for RTC, of course.

    Hi. Recommend what battery CMOS can be used? For example, cr2032 will normally work?
