What to do if I get 'Debug Power Request Fail' with my MDS E-PGM+ Microcontrollers?
If you encounter a 'Debug Power Request Fail' error, it might be because the reset IC in the board is in a reset state, or the tool-Vdd is lower than the Vdd of the reset IC. You may need to change Vdd from 3.3V to 4.5V.
What does it mean if my MDS Microcontrollers show 'Power Check Vdd : xx or Vpp : xx'?
This message indicates that the supplied Vdd/Vpp voltage is not correct. This can be caused by on-board writing, the target board spending too much current and dropping voltage, or a short between Vdd and GND during on-board writing.
What should I do if my MDS E-PGM+ Microcontrollers display 'CPU Reset Halt target'?
If you see 'CPU Reset Halt target', it means the device is in a reset state. Check the LVD of user option, especially if you are using A31G112/123. Set VDD as higher than LVD level.
What does 'Fail:Ext. Power On Remove Ext. Power' mean for MDS E-PGM+, and how do I fix it?
This message indicates that the target board is receiving power from an external source during on-board writing. Remove the external power.
Why does my MDS Microcontrollers show 'Trim Chk. failed'?
The 'Trim Chk. failed' message appears because no device-special-data is found, or the device is reset during on-board writing.
What to do if I encounter an error when executing E-PGM+.exe with MDS Microcontrollers?
If you encounter an error message when executing E-PGM+.exe, it may be because WDAPI1010.DLL is not in the C:\windows folder. If you set up the device driver, it can copy to the C:\windows folder.
