JTAG Interface using a STM32F103

I want to develop a JTAG interface using STM32F103. One way is to use GPIO to drive/read the signals, another way is to use SPI, but unfortunately TMS signal is not present. Is there a way to use SPI and simulate a TMS sincronous with SPI clock ? Any other solution? Any suggestion is well come.

best regardsGian #stm32f103 #spi #jtag

The forum does not like mobile devices.

You'll have to decide if you can deal with the pins clashing or not. There are definitely a number of things to consider if you're doing boundary scan.
