Rock Pi 4B+ no boot, no video

#1

Hello fellow experts! :wink:

I recently bought a RockPi4B+ v1.72 with 4Gb DDR and eMMC 128Gb (soldered).
First, I connected the HDMI and powered via USB-C (PD, not 5V, as per instruction). Green LED lit, but no video at all.
I assumed that the eMMC is empty, so tried to flash it by following this instruction using RKDevTools.exe. The used Loader was rk3399_loader_v1.20.119.bin and UBoot image rockpi4b-uboot-trust-spi_2017.09-2697-ge41695afe3_20201219.img.
First problem I encountered was the missing Image name in in Download Image section of the RKDevTools, so I used the Uboot name itself as shown below:

RKDevTools_1

I don’t saw any error in this screen. The log file contain these records:

Once done, I removed the jumper for SPI1_CLK to GND, reconnected the HDMI, inserted the uSD card containing this image (Raspbian Pi Lite btw) and powered the board.
Result is the same, no video, no boot, just the green LED lit.

Any helpful idea really appreciated!

Thank you!

Hello again!

I see nobody replied here, so according to other posts, I tried again, this time with RKDevTools 2.84.
The used Loader still rk3399_loader_v1.20.119.bin but the image is a Debian one from here (rockpi4b_debian_buster_xfce4_arm64_20210824_0233-gpt.img). Again, the RKDevTools doesn’t have folder name as “Image” so I loaded the Debian image in “Uboot”:

The log file is also similiar, ended wit exit code -1 and contain error:

At the end of process, the tool reset the board and lit the blue LED (no info found about the meaning).
One I removed the maskrom jumper and powered the board, both green and blue LED lit, but no video on HDMI. On network, MAC address is detected, but no port listening at all (tried 22, 80, 8080).

I’d really appreciate if anybody can help this time.
Thanks in advance!

Hi, it looks like the Androidtool is trying to find the parameter, which is not available on gpt images.

Please try with the 2.69 version with pre-configured partition info:
