Module is SoC module, with GPIO port, program download using ASR official test board;
Connect XRES, SWD_CLK, SWD_DATA, GND, 3V3 of the test board on the official website with
XRES, SCLK, SDAT, GND and 3V3 of the downloader respectively, and ensure that both green lights
are on before downloading. If there is any exception, please press this button to ensure that both green
lights are on. (for details, please refer to the official ASR6501 burning instructions)
