Description
The DAPLink made by myself can worked in iar, but in keil_ MDK can recognize the device, but RDDI-DAP Error is displayed during burning. What is the reason for this? The wire on the SWD end is already very short, only 20cm.
And there were no USB drives with the drive letter daplink
Can anyone provide any suggestions?
I am using the latest firmware and the system is WIN7

Contributor guide
Research direction
Reproduce the failure with the self-made DAPLink on Keil MDK while comparing the working IAR setup. Check the RDDI-DAP error, SWD connection, firmware version, and whether the DAPLink USB drive appears on Windows 7. Done means identifying and documenting a verified cause or fix.
