After installing et testing every kind of drivers you gave me, the result is still the same sadly  :(

I also tried to disable firewall but still same result
The thing that i don't understand is that we have an other computer with windows 10 and the same settings/hardware and it works for them. They installed it with Zadig too.

Quote from: LubOlimex on March 05, 2024, 12:53:07 PMGPIO0 should NOT be pulled-down during power-up or reboot or your code won't execute, you will set the board in different mode. This is visible in the bootable in the schematic.

My intention is not to do a pulldown, but quite the opposite, a pullup. But anyway I will do previous tests.

Thank you very much for the time dedicated and the support provided.

Yeah they are old, before Windows invented signed drivers and driver signature enforcement. You need to disable temporarily Windows "Driver Signature Enforcement", install the driver for the tool, and after confirming it works, restart the PC to re-enable the "Driver Signature Enforcement". Disabling the driver signature enforcement differs between different Windows versions but it is usually like that:

1.1. Click the Start button and select Settings (do not confuse it with Start Menu Settings).
1.2. Click Update and Security.
1.3. Click on Recovery.
1.4. Click Restart now under Advanced Startup.
1.5. Click Troubleshoot.
1.6. Click Advanced options.
1.7. Click Startup Settings.
1.8. Click on Restart.
1.9. On the Startup Settings screen press 7 or F7 to disable driver signature enforcement.
1.10. After disabling the enforcement, DO NOT RESTART your PC, else you would have to start from step 1.1.

If you have problems with disabling "Driver Signature Enforcement", notice that there are many resources online on how it can be done. My advice is to use the manual method without permanent disable, just temporary.

After you have managed to disable the signature enforcement, install the driver manually (point Device Manger to the file inside) and test if it works. Notice that if you change the USB port, you would need to re-disable the enforcement and re-install the drivers so make sure to keep the same USB port that you are going to use long term.

You might also give a try to these drivers:

ESP32 / Re: Doubts ESP32-POE

10kOhm is alright. Current 50nA at least that info can be seen in the user manual for the ESP32 chip in "DC Characteristics" table.

GPIO0 should NOT be pulled-down during power-up or reboot or your code won't execute, you will set the board in different mode. This is visible in the bootable in the schematic.

The target is a franking machine, the connection is actually like this :

 Board of a franking machine connected to a FP E204470 D1 94V-0 board connected to the ARM-USB-TINY-H probe connected to the computer by the front usb port.

I can't install those FTDI drivers. It says that the file is damaged of falsified.

1) In the first screenshot the problem is not in the debugger or the driver. It is properly recognized. It appears like wrong hardware connections.

What is your target? How is the JTAG connected to it?

2) The second screenshot is ancient OpenOCD version 0.1.0, if you are using the ancient OpenOCD, you probably need ancient drivers. Try the FTDI drivers, they require manual installation and pointing. First uninstall the zadig drivers. Here you can find very old drivers:

Hello !

To explain what "init com" is, it's simply the communication between arm usb tiny h and the franking machine.

I tried the OpenOCD and line command and i get this result (i also added the cmd error when i use my launcher) :cmd test

ESP32 / Re: Doubts ESP32-POE

Hello @KeviNH @LubOlimex and thanks to both of you.

Decided, I will mount ESP32-POE-ISO WROOM. There are quite a few plates I have to make and it's not worth the risk.

What current is necessary to activate an ESP32 input? In order to calculate the resistance on the transistor side of the optocoupler.

I am not going to use GPIO0 at first, but I want to leave it ready in case it is necessary. It is used during the board's startup. Could it be a problem to install an external pullup resistor? Could it affect startup?

Thank you.

Yes, what Kevin wrote - it is highly recommended to have USB-ISO or similar product between ESP32-POE boards and your computer or power supply, this would reduce changes of influence between LAN and the USB. We also use USB-ISOs in our tests setups for ESP32-POE (each ESP32-POE is tested here).

ESP32 / Re: ESP32-POE2 details coming?
Last post by LubOlimex - March 05, 2024, 09:32:07 AM
The design ESP32-POE2 is shaping and in final stages. The big things about ESP32-POE2 over ESP32-POE - the 25W  total output, 12V DC output available on the header when powering from POE, and the availability of JTAG signals.
