And I guess that's the right thing to do. > Can you check > 1) That you have sufficient pull-up on the nTRST line? (check visually, > measure > nTRST voltage after openocd start). Yes, and if you have nTRST actually connected you should just include it in the reset_config if you count on it to provide the stable level, that will work regardless of the pull-up. And if you prefer to not connect an extra wire, then you need to have the pull-up on the nTRST line either on the target board or inside the SoC (as e.g. stm32's have). > 2) If "reset_config srst_and_trst separate srst_gates_jtag srst_open_drain > connect_deassert_srst" makes any difference. > 3) If "reset_config srst_and_trst separate srst_gates_jtag srst_open_drain > trst_push_pull connect_deassert_srst" makes any difference. I think both are the same and are default + srst_and_trst, so basically the test would be to change srst_only to srst_and_trst in the config.
