Solve PSG9080 black screen caused by firmware upgrade
(1/4) > >>
Junce:
When you use a new PSG9080 to upgrade the old version of the firmware, there is a black screen that cannot be used.

You can power off the PSG9080 first, then keep pressing the number button 8, then power on the PSG9080, then briefly press the power button once to release, and finally release the number button 8, you can get the firmware upgrade interface.

Then you can open our firmware upgrade software

Software download address:
68.168.132.244/PSG9000/FWUpd2.exe
Firmware download address:
68.168.132.244/PSG9000/P9080swm.bin

1. Open the computer port corresponding to PSG9080
2. Open and select the firmware upgrade file
3. Run
4. The operation is successful
5. Click to exit
6. After the appeal steps are completed, the machine is powered off and restarted

As I know there are at least two PSG9080 generator versions. One version uses STM32F103RCT6 controller for the front panel and another version uses another controller with another PCB layout. Both version have the same PSG9080 name, the same version name and reporting the same firmware and FPGA version. But of course they are different and firmware incompatible with each other.

For what hardware version your manual is intended for? And what hardware version is compatible with firmware from your link?

Attempting to upgrade firmware when you don't know exactly if it is compatible with your hardware leads to device brick. And black screen issue.

The problem here is that manufacturer has exactly the same device name for very different and incompatible hardware versions. And the same thing for firmware - different firmware version have exactly the same version name. That's a big mistake which leads to device brick issue, because there is no way for the user to distinguish different hardware and firmware versions.


by the way, the software check shows that the latest firmware version is still 1.20 which never changed from 2020 year:

As you can see this is reported from the same server on which you place a new firmware... So, why it didn't show that update?
radiolistener:
For example the first picture is a front panel PCB of my PSG9080.
And the second picture is a front panel PCB of fjalvingh PSG9080.

As you can see they very different, with very different layout and it seems that the second one microcontroller is not STM32.

But both have name PSG9080, both have the same version for firmware and hardware. And both have the same display, buttons and knob.

So, for what hardware version your new firmware is intended for?
Junce:
When you have an old machine in your hand, and then flash the new firmware, resulting in a black screen, you can flash back to the old firmware to solve the black screen problem
Junce:
Thank you very much for your reply,
The so-called old firmware corresponds to the product of the STM chip
The new firmware corresponds to the new chip and the new layout of the product
Therefore, the new firmware and the old firmware cannot be randomly flashed. They must correspond to each other, otherwise there will be a black screen.
