JTAG

Hello is it possible to connect with standard JTAG to the Firefly RK3288 board? I saw the pins TDO... go to the SD card socket, but would it work if itis removed? We would like to port our RTOS to the board

other RTOS？It is so?interesting

"ther RTOS？It is so?interesting" doesn't answer my question.

You can use the UART or mini USB for debugging.

You cannot use UART debugging for baremetal and it is crap compared to JTAG debugging. And it was not my question.

I am not sure about it. I only have experience about printing device and if you want to know anything about it then do let me know I will guide you about it properly.

The Firefly RK3288 board does not have a standard JTAG interface built-in. However, it is possible to establish a JTAG connection by using an external JTAG adapter or debugger that is compatible with the RK3288 processor.

It seems unclear to me. I only have experience with printing devices, so please let me know if you have any questions; I'll be happy to help.

You mentioned that the JTAG pins (TDO, etc.) are routed to the SD card socket. This is somewhat unusual but not unheard of; it could be due to board design constraints
