ETM not working on stm32f7

Bilal

Hi,



i am using stm32f7 and for debugging ulink pro, i have tried to enable ETM but not succeeded.

the connector i am using is,

trace_D0          PC0

trace_D1          PC8

trace_D2          PD2trace_D3          PC12

i downloaded 2.4.0 tried running it on the above pins, not worked. but then i changed my pins on hardware to PE3 to PE6 and removed ini file, trace started working.

i came to know from a guy on keil forum that software pack (2.4.0) supports pins PE3-PE6, and i have to disable that option if i want to use the above mentioned pins and add ini file and initialze those pins in ini file. i have tried it but it is not working.

my ini file is

i have changed the core clock to 180MHz. 
Where am i doing it wrong ?
Thank you
