RK3399 - Flashing eMMC with HDMI - IN

silviogreuel

Hi,

Testing RK3399 for a big use case (1k+ devices) regarding HDMI-IN and HLS (live streaming)

RK3399 attended all requirements, but, I couldn't flash a image into the eMMC:


- Using upgrade_tool give me a Loading firmaware error,
- Tryed then a armbian image, worked using the armbian script, but, without HDMI-IN because armbian doesn't support it
- Tryed again upgrade_tool, but now, none devices are listing

What can I do now? I really fucked up installing armbian on eMMC?
Could I change this script somehow? https://github.com/orangepi-xunlong/OrangePiH3_scripts/blob/master/install_to_emmc


Thanks in advance...

You should try to get your board into MASKROM mode with the test pads.
For some other boards, there is a script that will write zeros in specific parts of the eMMC, so that the board thinks the eMMC is empty/defective, and then gets into MASKROM mode.
I did not manage to get it working with my OrangePi RK3399 boards.

Just can't update emmc.

Either using the mega.nz images or compiling my own with the https://github.com/orangepi-xunlong/OrangePi_Build.

Using flash_tool.sh

./flash_tool.sh -c rk3399 -p system -i ../output/images/OrangePi_rk3399_xenial_server_v1.0.img
PARTITIONS OFFSET: 0 sectors.
The device does not support this operation!

With upgrade_tool, device shows up, but keep getting:
Rockusb>UF OrangePi_rk3399_xenial_server_v1.0.img
Loading firmware...
Loading firmware failed!

Don't know how to proceed now, feeling that money was wasted on this board.

Managed to write OS on eMMC:

Tried (several times) starting the board on MASKROM mode (steps from manual):

• Power off the device
• Use metal tweezers to keep TP50265 and GND connected
• Power on the board with DC
• Wait a moment then release the metal tweezers
• Use a micro USB Type-C cable to connect device and host PC
• Device should enter MASKROM mode
  

PS.: Only worked on my USB 2.0 port.

Once entered MASKROM mode, I ran the command:

./flash_tool.sh -c rk3399 -p system -i ../../OrangePi-rk3399_Debian9_20181016.img

The image above was downloaded from the mega.nz.


Board restarted and booted debian from emmc.

Feeling dumb now, not wasted money at all


At last but not least, a quote from my country:

"Obrigado a todos os envolvidos"

Hi Silvio,

Glad to see that you have solved your problem as well.
I faced a similar issue, and followed similar steps as well.

Another thing, Silvio, did you managed to get the HDMI IN working?

When flashing eMMC with HDMI-IN, understanding the concept of a referral ID is crucial. A referral id example, could be "FLASH123" or "HDMI456". This unique alphanumeric code allows users to refer others to the service. By sharing their referral ID, users can earn rewards or benefits for successful referrals, fostering community engagement and driving growth within the eMMC flashing community.
