Finaly I understood why this procedure with flashcp doesn't work as it did with previous images. U-boot is split between spl.bin and u-boot file. Previously it was one file with all-in-one. So I don't know how to flash to SPI-NOR with two files. Anybody with ideas are welcome.

Hello, I tried your solution, but I am doing something wrong, flashcp doesn't output nothing. Is that right? When I connect HDD and try to boot, I get error
Trying to boot from sunxi SPI
No matching DT out of these options:
Configuration to load ATF before U-Boot
No matching DT out of these options:
Configuration to load ATF before U-Boot
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###What am I doing wrong?

What do you mean by "new procedure" ?
Previously this year I asked about boot from USB without SD card. Solution was flashing u boot to spi flash. With this new image doesn't work. So I would like to know how to update u boot on SPI so it will boot from USB without SD card.
Thanks

Thanks in advance.

Hello,
today I've got my 2g-IOT. I have found that it uses 40-pin LCD connector. Which LCD is suitable for this?

Hello,
finally I understood what do I have to do. I have checked timings with .bin via fex. Then I recompiled kernel and installed to SD card. But I have problem: when I check via fex I get resolution 1280x720 instead of monitor's 1280x800. I have compiled with 720p, but the picture isn't sharp, but when I change 720 with 800 I don't get picture. Please help.

Can anybody help?

Hello,
I have another issue, only on 720p and 1080p is picture with normal colours. On other is green and pink, so it doesn't work.
Reply on previous comments: I have checked this topics, but I haven't found where is this patch put? In which directory?
I have also tried SD card with h3 disp helper, but it didn't boot, probably because is made in VM. Is there another solution for Windows image burner?
I am complete newbie on LCD timings, so please help me.

Hello,
I am opening new topic because I simply cannot get monitor running on 1280x800. I only get shrinked picture, that isn't that I am looking. I also cannot understand how to add new resolution to kernel.
Please help, thanks all in advance

Which LCD is supported on this model? Connector looks like as on 4.3 inch reverse car LCD. Has somebody solved this issue?

Yes, should be either
dd if=u-boot-sunxi-with-spl.bin of=/dev/mtd0block
or
flashcp u-boot-sunxi-with-spl.bin /dev/mtd0
flashcp is present in the "mtd-utils" package
Thank you very much! The flashcp made the work. I didn't know to what package is this utility included, since that dd did nothing. Thanks again.

Not exactly "usable", but possible to use.
First, write the u-boot (u-boot-sunxi-with-spl.bin located somewhere in /usr/lib/linux-u-boot-dev...) to the SPI flash, either with dd to /dev/mtd0block or with flashcp to /dev/mtd0. No offsets are needed for dd.
Second, write a fresh image to the USB HDD. Old images (even after upgrades) or installed with nand-sata-install may not work and were not tested.
Third, shut down the board, remove the SD card, power it on and hope that your HDD spins up fast enough. U-boot has a timeout for detecting USB devices that AFAIK can be changed only with recompilation and if HDD spins up long enough it won't be detected.
If there are any questions or issues, they will not be looked into without a log from the serial console.
dd if=u-boot... of=/dev/mtdblock
Is this right command?

Hello.
Maybe stupid question to ask here. Is Orange Pi Zero NAS compatible with PC2?
Thanks.Yes it is but you need some soldering skills to connect to USB on PC2

Hello,
did somebody find SPI flash usable? I am thinking about boot redirect to HDD on USB. Has anyone idea how to make that?
Thanks
-
Good work team, congratulations. I have already tried it, installed on hdd with nand-sata-install, but I am thinking if it's possible to remove sd card, and have boot files on SPI flash. Is that possible?
-
I have received PC2 today in Slovenia. Board will wait till Armbian distro comes out.

It sounds like really faster upgrade, but where is promised OPi micro/ RPi zero alternative?

Hello,
I was looking to do soldering usb part, but I don't know which pin is positive and which is negative. That marks in front of pins dont tell me which is positive and which is negative.
