Hi I was trying to burn Android Firmware to EMMC on my Edge-V using burn-tool :

mohit@mohit-H110M-S2:~/Downloads/Edge_Nougat_V190624$ burn-tool -v rk -i update.img 
Try to burn Rockchip image...
Burn to eMMC...
Rockchip Android image (or linux image compatible with AndroidTool one image burning) found!

Upgrade firmware ok.
Done!

Then I landed up in Android Recovery, I tried to flash the Nougat image again :

@theperfectpunk, Can you re-insert type-C and re-burn.It maybe just a accidental forehead error.Can you use a serial tool to connet the board.Serial ports print a lot of helpful information. We need it to analyze problems.

Hi @Frank
I have ft232r serial to USB converter, Can you tell me what GPIO pins to connect on Edge-V and the baud rate to set?

@theperfectpunk , There is the docs about how to connect you serial tool.

Hi @Frank ,

@theperfectpunk, try to use txt mode to eter upgrade mode and re-burn it . This is because the firmware of the last burning is incomplete and some of the contents are missing.

7

@theperfectpunk ,Because burning tools under Linux are a bit unstable, you can also use windows burning tools.If burning half fails again, that suggest using tools under Windows or burning Ubuntu firmware.

Hi @Frank,

when I try to enter tst mode, it doesn’t get detected

@theperfectpunk If you enter upgrade mode by tst mode. No information will be printed, you can confirmation by observing the light. You will see the Power-LED (Blue) blink for about 3 seconds. After the Power-LED (Blue) turns OFF, this indicates that the board is in Upgrade Mode (Maskrom Mode).And that you can burn the firmware.

Hi @Frank
I tried entering TST mode, but it doesn’t get detected (checked lsusb). Is there any way I can get working from u-boot. I am able to access u-boot, can I flash the whole firmware from there?.

@theperfectpunk Are you sure your connection is correct? It can enter the TST mode in any case.
