TDO/TDI? #19

Closed koendv closed 2 years ago

koendv commented 2 years ago

in dap.c I find:

  if (select & DAP_SWJ_TDI)
    DAP_CONFIG_TDO_write(value & DAP_SWJ_TDI);

but I do not find a HAL_GPIO_TDO_out() This is strange.

While functions are present, otherwise things will not build, the write must actually happen to TDI, not TDO. The pins are marked from the target point of view.

I fixed that.

Thank you. Will be using free-dap with Sipeed Longan Nano, GD32VF103 processor. Happy Christmas.
