Hello,
We are trying to switch over our part programming to use CMSIS-DAP, since
some of the newer parts we work with only support SWD programming. Our
specific setup is the new Atmel ICE (EDBG version) with the Atmel SAMR21.
We have it all working, but programming the flash is very slow (~1kB/s). To
do some tests, I chose one of our other SAM4S platforms that can do both
JTAG and SWD programming. Using a Segger JLink vs the Atmel ICE is like
light and day (with same adapter_khz settings).
Does anybody else have this problem, and maybe a solution for it? Or does
anybody have an idea where the bottle neck could be? I started to look at
the SWD signals, and there seems to be a lot of wait time between commands
on the bus.
Cheers,
- Thomas
