  1. Under a dozen developers, seemingly hundreds of boards. I think between lack of hardware in developers hands and really low download numbers were primary reasons.

    Rock64 Revision 3.0

    I'll be able to check later, but the SD is ext4, and I am moving the same physical SD between the two revisions of the board without any other changes. I did a lot of other tests on my own earlier on, MMC 0 is not present (and is not installed, so ok). Sent from my Pixel using Tapatalk

    Official Asus Tinker Board Case

    I would guess using the chiptenna it suffers significantly. That would be why there is a hole on the same side as the SD card to mount an external antenna and use the connector on the RTL8723BS

    Same. At $100 it fits in nicely.

    Switching Rockchip64-DEV to 5.0.y ...

    Hi@Ayufan, perhaps then I will focus on the Renegade, I was starting to get into the code last night for mainline u-boot. Have you seen my concerns with Rock64 rev 3? Sent from my Pixel using Tapatalk

    Rock64 Revision 3.0

    I don't think this has anything to do with the drive strength, I can scan different SD's with no issue, reading the mfg info/type/size/etc. But it won't recognize the filesystem in any of them. (Tried 6 different ones) Sent from my Pixel using Tapatalk

    Rock64 Revision 3.0

    Sorry I didn't get back to you, but here goes: => mmc list rksdmmc@ff520000: 0 rksdmmc@ff500000: 1 (SD) => mmc info Device: rksdmmc@ff500000 Manufacturer ID: 3 OEM: 5344 Name: SL16G Tran Speed: 50000000 Rd Block Len: 512 SD version 3.0 High Capacity: Yes Capacity: 14.8 GiB Bus Width: 4-bit Erase Group Size: 512 Bytes => ls mmc 1 ** ext4fs_devread read error - block Failed to mount ext2 filesystem... ** Unrecognized filesystem type ** Now, to be completely clear, that SD card boots perfectly on a revision 1 board. I was talking to Pine, I think I might have to reach out again.

What options and hardware combo would wreck reading the SD card? *head explodes*
  10. Probably a good question, are you concerned about emissions from the SBC or immunity of the SBC to outside noises? Obviously increasing drive levels makes the square waves more square, meaning higher frequency content. For immunity, my guess is conducted immunity through the power supply is a touchy spot, being supplied 5 V and running on 5V, no chance to avoid noise.

    Rock64 Revision 3.0

    Mmhmm. my V1 has no problems with our u-boot, it is fine from eMMC and from SD. The V3 is fine from eMMC if I 'transplant' it from the V1 to the V3. SD using our u-boot recipe somewhere goes wrong on V3, so I need to debug

    Rock64 Revision 3.0

    Hi @Thewonderer, I have dev samples of a few boards, it's one of the ways we work with vendors that show interest. My other Rock64 is a pre-V1, so I wanted to make sure I had something representative moving forward. I've had some personal projects going, and @martinayotte moved so much around on these boards I decided to stay out of the way. Taking a look at the u-boot configs and device trees tonight to see if I can find a difference, the Renegade image got to the point of loading kernel (obviously didn't get past that with the differences in DTS's) on the Rock64 3.0 while the Rock64 V1/2 image would not, telling me there's no hardware issue. @martinayotte did you try to boot Renegade with newer u-boot? I can't remember if you have one or not.

    What is "TinyCore" ?

    I ran tinycore on some PC's a long time ago for experimentation purposes. I check back from time to time.

    Le Potato - writing armbian to eMMC

    Agreed. I'd forgotten that, for standard Armbian nand-sata-install works, but you have to boot Armbian first to get that far. I wasn't able to brick it on purpose using the USB burning tool because it's built not to allow it. (Of all the things for them to do right...)
