I'm trying to use jlink with a 100kHz cJTAG like this:
JLink.exe -if cJTAG -speed 100 -jtagconf -1,-1 -autoconnect 1
I noticed that jlink does not set the clock frequency to 100kHz at the beginning when connecting to the device, but uses a clock of about 400kHz independent of the frequency requested.
Only later, after some initialization, the clock is set to the target frequency.
I was wondering if that is correct behavior, or if this is a shortcoming of jlink.
Anyways I'm having connection issues with my device and it seems that too high of a clock frequency is the reason.
So I was wondering if it's possible to force jlink to use the specified clock frequency at all times.
PS: it seems that jlink starts with the slowest frequency it supports, which seem to be about 400kHz. Is that correct? No clock frequencies slower than 400kHz can be used with jlink?
