Troubleshooting
Device ID does not match
At the start of the programming process, the Flasher attempts to connect to the device and read its device ID. Each Aurix device has a unique ID.
If a device ID error occurs, there may be several possible causes.
To obtain detailed information on the error, increase the "Verbosity level" in the U-Flash configuration to at least "Detailed" and transfer the project to the Flasher again.
Device ID = 0x00000000 or 0xFFFFFFFF
- There is a fault in the wiring
- The device is kept in reset by an external reset generator or watchdog
- The supply voltage is insufficient
Device ID is wrong
- The wrong device was selected in U-Flash
- There is another device on the board assembled
- The supply voltage is too low and/or the interface speed is too high
