Rock 4C+ v1.41 not booting

[opetany]

I have a project developed on Rock 4C+ v1.2 board. Now there is only v1.41 board available and Armbian is not booting on it at all, no matter it's compiled locally, or it's downloaded from the official sources. 

UART debug is producing unreadable sequence. 

 

So far, what I’ve tried:

- I’ve built Armbian with the latest changes armbian build repo - hasn't helped

- I’ve used rk3399-rock-4c-plus.dtb file instead of rk3399-rock-pi-4c-plus.dtb, dunno why there are two, but somewhere on the forum I read that this one without “pi” is the right one - hasn't helped

- official Armbian images - not booting

- Ubuntu and Debian - both booting fine

 

can someone help?

@opetany My latest Armbian builds (and even downloaded ones) were not booting. Have a look at the solution I posted in this link Issue on github.

 

Edit "/boot/armbianEnv.txt" (actual path may vary where you mount your sd-card / emmc module). Ensure the entry for fdtfile looks like following:

 

fdtfile=rockchip/rk3399-rock-4c-plus.dtb

Using this fdtfile, it seems that the NVME on my 4c+ is no longer listed as a device.  Is this a known problem?

I meant exactly what are you saying, but still thanks for your interest! In the end, we came to the assumption that we have some faulty batch because on others 1.41 boards everything works correctly.
What is interesting, all boards on which Armbian can't boot up are with white legend text on PCB. These 1.41 on which there are no issues with booting are with black legend text, so maybe radxa changed a factory or something different weird happened. Anyway, we decided to go with the well known and reliable rpi 4
