The current version of Keil MDK (v5.38) ships with ULINK drivers for x86 and amd64.
Are there any plans to release Windows 11 compatible drivers for ARM64 in the near future?
There won't be ARM64 support for µVision. But this does not affect i.e. the ULINKpro driver support by Windows 11 in combination with Intel/AMD PCs.
