Need help with TX3 Mini with Rockchip 2338A, pins to short for mask mode?
Need help with TX3 Mini with Rockchip 2338A, pins to short for mask mode?
Hi all,
Can anyone help with this strange new SoC which was advertised as having an Amlogic S905X2 but seems to have Rockchip 3228A?
It is no longer getting into flash mode on Batchtool 1.8 and unsure which pins I would need to short, not even sure where the nand is tbh.
So I think the eMMC is this 5KA98 / JY941 which has nand onboard. I tried shorting pins around the IC and the red led has briefly gone blue but cant seem to isolate the exact pins.
I looked for a pinout diagram online but not really sure what I am looking for exactly.

Hello, did you find a way to unbrick this device? I have a similar board to yours and while trying to install Armbian on it, it stopped booting and only shows blue light.
From what I read on the description, this board of mine has EMC, as MXQ_RK3229_EMCP_V4.0 is written on it, that's means :
There are however some unfortunate cases (expecially newer boards) where shorting the eMMC clock pin is difficult or impossibile, like eMMC or eMCP BGA chips with no exposed pins. In those cases pay double attention when burning something on the internal eMMC/eMCP and always test first the image from the sdcard to be sure it works before burning anything on eMMC/eMCP

From Red to Blue is good sign ..
Even briefly...
Keep Trying points...
Sometimes can be simple Thing that is missed in Process
Close Batch Tool
Uninstall Driver Assist..
Then Reinstall Driver Assist
Open Batch Tool Load file
Repeat every time you test a different Rom
Here is observation From OP image posted 3rd down from top
Reads as /ncXQXT6..
To the Left of Vertical Sticker reads as TX3-R29-LP3-V1.0...
Approx 1. 5 cm are 2 copper circles/points on a Diagonal
Maybe bridge those...
Best is to leave this Thread and From Home
Move Down to Rockchip based TV-Players

FreakTab Tools and Utility Collection thers are Stickys/THreads that will help with Unbrick
Thanks all, appreciate the ideas. I'll try to bridge some of those pads you've mentioned.
Do you know if there is any variation in the maskrom initial handshake process? I read most places that you have to have the physical reset switch depressed while also shorting the pins. Then with all that in place simultaneously insert the USB cable to give power to the circuit?
Is this standard procedure or do different SoC manufacturers have other procedure?

Hmmmmmmmmmmmm
You are confusing yourself with what you read ....
That is one method to Connect Box to Batch Tool
Minus the short Pins /Nand
It is next to impossible to physically attempt such a procedure
You dont have enough Hands....
Ha Ha ha
