Hello I'm a beginner but have read a lot about it,

My VU+ DUO2 only shows a white LED, so I want to flash the bootloader again. But for my chip k9k8go8uod I Need a BCM7424 but I can't find anywhere. I would also like to know which Jtag port I can use, the P703, P401 or P301? I bought the Cypress CY7C68013A EZ-USB FX2LP on eBay and it should arrive in a few days.

Can anyone help me? I'm grateful for any advice.

As far as I known is there no bbs software for these BCM7424 cpu, as also no nand flash script.
Jtag pins question, I think, the four pins P301

Issue, white LED
Be sure that it failed to read from the usb ports, use a usb stick with an activity led, or monitor it with the rs232 terminal programs as putty to see if it"s doing an attempt to read from a usb stick.
You could also try to add the force.update to the usb files.

Thank you for the quick reply.

The receiver is dead. Nothing is shown on the display, except for the white LED.
The USB stick is also not getting read at the USB port.
With Putty no movement is indicated at the rs232 port.
I found a k9k8go8uod.xml file for the Vu+ Ultimo and inserted it into the BCM7413 software.
I am just waiting for my hardware CY7C68013A from China to arrive, then I'll start some tries.

I'm grateful for any help.

Yeah well I have so my doubts if this BCM7413 will connect to the BCM7424, but it's worth to try.
Or maybe the BCM7429 will make a connection.

But did you also have tried to hold the front push button, and switching the box on.
It must be fully turned off, and at least for a few minutes before you can try it.

I can only try this when I have the Cypress CY7C68013A EZ-USB FX2LP.

Where can I get the BCM7429?

I have already tried pressing the front button whilst turning the device on.

You can download it here, it an topic for the Xtrend ET8500 which has this bcm7429 cpu.

Thanks, I'll test it soon. I was able to install "Bcm97429CBSetup.msi" but "BBS3 - setup.exe" is not installable.

I re-installed the software BBS 3. It is running now. The delivery from China doesn't seem to be coming yet.
Now I also ordered the TL866 Plus Programmer, unfortunately I will have to wait for a few more weeks.
In the meantime I measured the voltage on the P301 port, from left to right 3.3V, 3.3V, 3.3V and GND would this port be suitable for Jtag?

Actually, when you measure it precisely then it should be 3.3v, 3.2v, 3.2v, Gnd.
Thus, Vcc, Scl, Sda, Gnd
However since the cypress board already has his power from the usb, you only need to connect the Sda, Scl, Gnd, and yes it's based on the amount of pins, and measurements suitable for jtag.

TL866 Plus Programmer, good choice due the clone option and also one of my favorites.

Today I recieved the TL866II Plus Programmer, could you help me with the pin assignment? :

TL866II Plus----------------VU+ Duo2 Board P301

1. VPP- MCLR
2. VCC +5V
3. GND------------------------------ 4. GND
4. PGD - ICSPDAT ----------------- 3. SDA
5. PGC - ICSPCLK ----------------- 2. SCL
6. NC.

Is that right?
