Re: Debugging a signle register with JTAG

Which buses are involved here? How is the WDEV_RND_REG linked to the address given in the TRM (0x3ff75144)?

Thanks ESP_igrr

When debugging via JTAG, I still can see cases when I hover over a varaiable, it says "Optimized Out". Thanks and best regar...

Debugging a signle register with JTAG

Hi all, I have the TUMPA JTAG v2 board, connected to the ESP32 DevKitC board. The connection works fine and OpenOCD and gdb is properly setup. In my main.c, I am using the following function: #define RAND_REGCOUNT 32 // * 4 bytes = 1kByte uint32_t IRAM_ATTR esp_random_custom(void) { uint32_t retval;...
