RockPro 64 V2.1 Boot problem only DDR Version ... message

[nutilius]

Hi !

I have problem with starting any opsys from SD card.

When I try to boot, after switch the poer I see only message:

DDR Version 1.19 20190305
In

and nothing more

Previously I used different OSes (Armbian and NetBSD), but now I couldn't even go to u-boot (without sd-card I got nothing).
Any suggestions ?

My board is RockPro64 V2.1 2018-07-02

Have you tried a different sdcard?

Hi thanks for reaction.
Yes I've tried 3 different cards with different systems. Two of them worked before.

Is there a solution to this problem? I have the same issue and changing the SD card as well as the boot image did not work.

Are you using the serial console to monitor the boot messages? When I connected all three wires of the serial console, it didn't boot (I believe it got stuck at the DDR message as well). When I connected the ground and RTX only everything worked fine. See also here: HOW TO - Connect the serial console

I have only connected Ground as well as RX as described in the HOWTO you mentioned.

Since the last post I tried different thing like disabling the SPI EEPROM or the EMMC slot. All those thing did not help so put the board away for an evening. The next day the same SD card worked just fine. Since the SD card the board booted on was the "known good" SD card I powered down the board and inserted another card. After powering the board the serial console got disconnected and after reconnecting I got the same problem as described earlier. I just get the two lines and nothing else.
For me, this almost feels like there is a multifuse (or Resettable fuse) blown somewhere but I could not find one in the schematic. But maybe this is a known behavior but I could not find any hint of that in the Wiki. Next time the board will boot again, I will try unplugging the serial adapter completely before reconnecting the power cable.

I also had the board running for multiple hours with connected serial console but I did not reconnect the power cable.
