STM32F796NI Mbed debuging error

[JoanOG]

When I try to debug with the mbed studio I get the following error:

0001859:INFO:rom_table: [2] 0001860:INFO:rom_table: [3] 0001861:INFO:rom_table: [1] 0001863:INFO:rom_table:[1] 0001864:INFO:dwt:4 hardware watchpoints 0001868:INFO:fpb:8 hardware breakpoints, 1 literal comparators 0001876:CRITICAL:main:No cores were discovered!

Any idea?

please ask on the forum rather than docs (not related to the documentation).

Does pyocd work if you execute it directly? what version of pyocd or mbed studio is installed
