IDB Fail - impossible to update no Firmware

penguin

Weird. I personally use an ordinary macro usb cable, with a small Type-C adapter,
which is fine.

From your posts in http://bbs.t-firefly.com/forum.p ... page%3D1&page=2"Read Flash Info" does not return the correct flash size (only the wrong one, zero)

The SD card boot should work out of the box. But I'm afraid there might be something wrong the the HDMI connection.

The best way to know what is happening is to use a serial adapter ( http://wiki.t-firefly.com/en/Firefly-RK3399/senial-debug.html ),
which will get all the way from bootrom, u-boot, to kernel and rootfs.

@navigatoria
Please use AndroidTool_Release_2.58.zip in
http://en.t-firefly.com/doc/download/page/id/3.html#windows_12

AndroidTool 2.39 is not working with Ubuntu firmware.

Please try AndroidTool v2.58 first.

Any serial adapter support 1.5M bps is ok. It should be not hard to find in your Europe online shop.

I'd like to know how did you go to maskrom mode at last? Will you please spot the detail?

hi @navigatoria, I wish I had your "mini-screwdriver" too.

There might be something wrong with your eMMC flash.
In AndroidTool, when clicking the "ReadFlashInfo" button,
the correct flash size should be shown instead of zero in your case:



However, do not give up hope. You can try:

1. Use upgrade_tool in Linux OS to upgrade the firmware.

2. Use SD card boot, try other model of HDMI display.

3. Use SD card boot, with the serial adapter to monitor the boot sequence.

I've confirmed that the SD boot firmware Firefly-rk3399_xubuntu1604_SD_201705151725.7z
downloaded from
    https://drive.google.com/drive/f ... gAqAamx6cXd6b205eEk
is able to boot and the graphics window system is available.

After SD card boot, it can be confirmed whether your eMMC flash is broken or not.

Maybe the simplest way to use the serial adapter with SD card boot to detect the real culprint.

If the eMMC storage is confirmed to be broken, you can contact our service for warranty.
