RTOS/AM5716: How to print out floating point variable with using UART-printf to console port

Part Number: AM5716

Tool/software: TI-RTOS

I'm porting TI-RTOS for custom board of AM5716(SR2.0).

With seeing the UART_stdio.c, UART_printf can support only "\%c, \%d, \%p, \%s, \%u, \%x, and \%X."

I would like to print out float variable with using "\%f" on console port.

Please let me know the best way to do while USING MPU with TI-RTOS.

Hello,
depending on how much fraction digits you want to transfer you simply can multiply the value by 10, 100, 1000, etc. and then send via available UART_printf formatting. On the opposite side just divide the received number by same power of 10.
