I'm currently planning a personal project with the DA14531MOD. In this project, I would need to use all of the GPIOs. This includes the SWD pins (P0_10, P0_2 and the reset pin (P0_0). If I've understood it correctly, the debugger can be disabled in the firmware.
My question: is it possible to flash the module with SWD after I've once disabled the debugger?
Hi Markus,Thank you for posting your question online.You can burn the RAM with SWD to develop your project and after the initialization you can configure the P0_10 and P0_2 the way you like.If you want…
Hi Markus,Thank you for posting your question online.You can burn the RAM with SWD to develop your project and after the initialization you can configure the P0_10 and P0_2 the way you like.If you want to use the P0_0, you should first disable the HW reset and then configure it.All the configuration of PINs is inside the user_periph_setup.h and user_periph_setup.c file.If you want to burn the Flash of DA14531MOD, you can even use 1-wire UART or 2-wire UART. You can do that be using the SmartSnippets Toolbox: SmartBond Development Tools | RenesasI would also suggest checking our: DA14531 Booting from OTP and Serial Interfaces Kind Regards,OV_Renesas
