I have a custom pcb using an EFM8BB cpu
I can load via the USB debug adaptor but unable to set breakpoints/single step or run the firmware via Keil uVision V5
the USB debug adaptor DLL is SiC8051F.dll id V22.214.171.124
Is there an updte to this?
unable to set breakpoints/single step or run the firmware via Keil uVision V5
'native Keil or Keil under SS?
Thanks but problem now fixed, I found a post with the following.....
When designing the target board, you should place bypass capacitors (0.1 µF and 4.7 µF) between VDD and ground. C2CK should have a pull up resistor (no more than 10kOhm, 1kOhm recommended) to VDD. Do not connect any capacitors to C2CK
THIS FIXED MY PROBLEM...WHY DID SiLABS NOT PUT THIS IN THE REFERENCE MANUAL IT WOULD SAVE PEOPLE A LOT OF WASTED TIME !!!!!!!!
I only needed the 1K
Thanks for the feedback! This information should be available in the Debug section in the Typical Connection Diagrams chapter of the data sheet, so please check there for your specific device for this recommendation. I always recommend checking this section in detail before designing your hardware.

In my opinion the "reference manual" for developing hardware is the devboard schematic
decoupling caps is a mandatory for all chips, SiLabs uCs or not, is basic electronics
