BPI-R4 hangs at boot

charlesrg · November 7, 2024, 3:01am

I’m trying to boot my BPI-R4 but it hangs at boot. For example using mtk-bpi-r4-SD-20240620.img onto the SD card and setting the Dip switches to 1-1 I get:

I’ve also tried with the latest Openwrt Snapshot and the other Debian12 and Ubuntu from the “Getting Started Page” images but it is still not able to boot. I also tried the NAND and eMMC with no success. If I try Web Failsafe and upload an image over the Browser I get:

I tried different images but always get firmware integrity faiiled.

I tried different PSU to make sure that is not the problem but the problem still persists.

I’ve noticed this on boot:

Could that be a problem or anyone suggests anything for me to check ?

Which uart adapter do you use (please use ftdi)? Try removing all perpherals. If issue still persist it looks like your board is broken.

**NOTICE:  Unexpected CPU frequency measured**
**NOTICE:  EMI: Using DDR unknown settings**

Those seem to be normal as I’ve seen this by others that posted successful boots.

I continued to try many different boot images but it keeps failing. I’m starting to think that my board is defective.

charlesrg · November 7, 2024, 1:05pm

Yes, FTDI 3Volts. Tried many many images. I’m running out of options.

Could try this image, it boots without u-boot, so it could skip a possible cause… Although, with that error, it does not look like it will boot anything…

Needs to be written to a sd card.

Thank you. I’ve downloaded and placed the image you shared on a new SD card. It still gets stuck, here is the log of first boot:

Which power supply are you using?

charlesrg · November 7, 2024, 9:30pm

I tried with both 12V 1.5A power supply and with a USB-C 100W that I use for my laptop.

ericwoud · November 8, 2024, 7:09am

I do not think this is enough.

Should be ok, but there may be negotiation issues, where the required voltage is not present (fast enough)?

If you have a heavier fixed voltage supply lying around, I think it is worth a try.

charlesrg · November 8, 2024, 10:33pm

Just tried with another 12V 2Amps Adapter and it still same trouble. Also connected a Killawatt to see the consumption and it does not go beyond 7 watts while the PSU could technically provide 24 watts.
