MRS bricks LinkE when upgrading firmware. #21

This applies to MRS as well as the "Utility" program. In either case if Link firmware 2.7 is detected you can do nothing other than upgrade the firmware to 2.8. This seems to happen peacefully.... BUT.... The Link is bricked as a result.

MRS will not recognize the Link and Utility crashes (Windows closes it) as soon as a bricked Link is connected.

This was done in Windows 10 with 2 LinkE and 1 LinkR (?? LinkV ??). Anyone want 3 bricked Links??

Well - it seems that the problem may only be in MRS Community c1.40 I changed to MRS c1.85 and it recognized the Link boards and did another firmware upgrade which has the Link boards responding as expected.... still can't upload to the target boards though..

but I will close this issue as stated.
