Problem Description

1. First of all i burned the DIS_USB_JTAG efuse.
2. then i set in the sdkconfig these values:

CONFIG_APPTRACE_DEST_JTAG=y
CONFIG_APPTRACE_DEST_UART_NONE=y
CONFIG_APPTRACE_UART_TASK_PRIO=1
CONFIG_APPTRACE_MEMBUFS_APPTRACE_PROTO_ENABLE=y
CONFIG_APPTRACE_ENABLE=y
CONFIG_APPTRACE_LOCK_ENABLE=y
CONFIG_APPTRACE_ONPANIC_HOST_FLUSH_TMO=100
CONFIG_APPTRACE_POSTMORTEM_FLUSH_THRESH=16384
CONFIG_APPTRACE_BUF_SIZE=16384
CONFIG_APPTRACE_PENDING_DATA_SIZE_MAX=0
CONFIG_APPTRACE_GCOV_ENABLE=y

added target_compile_options(${COMPONENT_LIB} PRIVATE --coverage) and REQUIRES app_trace in every component that needs to be compiled with --coverage option
4. I connected the relative pins of the ESP-PROG to the board (GPIO2 to GPIO5).
5. I run the openocd command
6. run on another terminal telnet localhost 4444
7. Sent the reset command to synchronize the MCU with openocd
8. Sent gcov dump
9. On the telent terminal i got

Total trace memory: 16384 bytes
Connect targets...
[esp32p4.hp.cpu0] Target halted, PC=0x4FC18DCE, debug_reason=00000000
[esp32p4.hp.cpu1] Target halted, PC=0x4FF06142, debug_reason=00000000
Targets connected.
Connection closed by foreign host.

And this is what was printed out in the openocd terminal

openocd: ../src/target/xtensa/xtensa.h:294: target_to_xtensa: Assertion `xtensa->common_magic == 0x54E4E555U' failed.

Hi @RCapolungo I was able to reproduce with the same version, but not with a newer one.

Could you please try whether updating openocd (to master in this repo or at least latest release) solves the issue for you?

Hi @sobuch, I tried with latest release and worked, thanks :)
