Ticket Name: RTOS: Tda2xx uart can't output print message

Query Text:
Other Parts Discussed in Thread: TDA2 Tool/software: TI-RTOS 1). When I use ccs6 debug tda2xx board, ccs console can't output print message. file_path: vision_sdk/links_fw/src/rtos/bios_app_common/tda2xx/a15_0/src/main_common_a15_0.c In Int32 main_common(void) I put UARTConsoleInit(UART3_INST); UARTprintf(" \r\n***** A15_0 Firmware build time"); after compiling successfully and download it into board through simulation tool, nothing print out on serial port tool when I run it. attach is source file. 2021.main_common_a15_0.c /*

Responses:
Hi, I have forwarded your question to an expert for comment. Regards, Yordan

when will expertt contact me ? does the expert contact me by this forum or by email ?

Hi Xiangtong, Are you using the TI EVM for this test? The TDA2xx TI EVM does not have UART3 populated. If your board does have UART3 populated, you can check on the following aspects: 1. Has the UART3 IP PRCM been enabled? (Clocks enabled for the IP) 2. The pin muxing has been done properly for the UART3 lines to be sent out the TDA2 device based on your board schematics. Thanks and Regards, Piyali

Hi Xiangtong, We haven't heard back from you on this one.. Is this resolved? Thanks and Regards, Piyali
