Hello All,I have a T56 which is now not recognized by the PC.
once connected both leds are up and PC is not recognizing the USB device.
I tried all I could including recovery procedure by linking J1 pin 2 and 5, but no way to get it recognized.
In a few days I should get a PicKit 5 interface and I will test I can get connection with the PIC32MZ1024EFH144.
I also bought a brand new PIC32MZ1024EFH144 in case the one on the board will be broken.
However I think I will need at least a recovery firmware to boot the device so that the XGpro software can then automatically update the firmware.
Can anybody help me in providing me a recovery firmware to be flashed in the PIC32MZ1024EFH144 in HEX format?
is there any possibility to "create an HEX version of the "updateT56.dat" present in the Xgprog software for flashing it in the PIC32MZ1024EFH144.
Any experience about flashing PIC32MZ1024EFH144.
Thanks in advance for any support.
Best regards

OK guys a new update on my bricked T56.I got the PICKIT5 programmer and connected to J1.
Here below the result:
- Reading the Chip ID works and this should mean the chip is not dead and that probably the firmware is corrupted.
- I tried to put MCLR (pin1) to GND (PIN3) and then connect USB. This should be also a reset forcing the chip to run bootloader, but the PC is still not recognising the device. When connecting pin 1 to GND the led RUN is switching off, but when disconnecting switching on again.
- I tried connecting pin 2 to 5 but no result.
- I tried then to read the firmware, but I got the message "The requested operation failed because the device is code protected." which make sense because the chip is read protected.

All I can do now is to find a firmware to be loaded in the chip after a full erase which can allow at least the bootloader to be loaded in order the device to be recognized by the PC and Xgpro software can update the firmware.

I kindly ask the admin or anybody else who can help if this is possible and to share the firmware privately.

Thanks in advance for any support.

Hello,
After jumper pin 2 and 5 , connect cable, switch on and verify in device manager, if the device is recognized there in any way, or if yellow exclamation mark
is there, and if it is try verify/changing the driver, or with a clean install the xgecu app in another machine, and try there with new cable.
Driver is called Xgecu WinUSB Device , mine is at version 1.11.9200.16384.

Hope it helps

Hi Albano,did all test with different computers and cables with no success.
No way to have it recognized via USB.
Only way id responding is via ICSP but I have no bootloader firmware to be flashed.
Any other idea?

Hello Sergio,
1- Try xgecu Support at 532007590@QQ.com and/or xgecupro@gmail.com and ask for help, maybe they still have parts
if needed.
2- Upgrade the unit to the new T76, T56 is already out of production, as it give more current
to program better newer ICs at XGecu T76 USB3.0 Universal Programmer support EEPROM NOR NAND EMMC MCU GAL;Minpro/TL866II/T56 programmer Replacement IC tester , new adapter investment maybe needed, Adapters for XGecu T76 Programmer

Never use Usb Hub, unless external powered, and that hub connected to a machine port directly.

To help all of us, please, share and post here the solution you may find, also share channel you get answer, please.

Best Regards
