i use arm develop studio 2021.01 version "Debug hardware fireware installer " update Dstream fireware failed.
Progress bar stuck at 90%, prompt timeout
Hello, it seems the unit firmware updated correctly. If you power cycle, does it reboot successfully? If you connect again with the same firmware installer utility it should report that the unit now has v7.4.0 installed.
If not, you may need to perform a complete restore:https://developer.arm.com/documentation/100955/0529/Introduction-to-Arm-DSTREAM/Restoring-a-DSTREAM-unit-that-fails-to-boot
Thank you, i have fix it
