Hi,all
the Test Env is DS-5 and DSTREAM-ST and arm development board, When I execute csat.exe drr cmd , the error "Autotune failure. Please try to reboot target and select a lower frequency using the AutotuneMaxFreq config item." occured.
I can't solve this error with cmd "cfb JTAGAutoMaxFreq 2000" and "cfb JtagClockFreq 2000",
so how can I solve this problem,Thanks!

Hi, Stephen
thank you for your help! The issue has been resolved.
the fail proceed as follows:
csat -cs600
con TCP:.....
chain dev=auto clk=20000 is ok
autodetect read-rom is ok
now drr dev**.0 return fail
the successful proceed as follows:
setprobe DSTREAM-ST // the default is DSTREAM
cfb ScanChainJtagFreqs 20000 //the default is 2000T
cfb JtagClockFreq 20000
cfb JTAGAutoMaxFreq 20000
now drr dev**.0 return ok
our traget is a emulation device with low speed.
thanks.
Thanks for letting us know that this problem is resolved :)
