RTOS/TDA3XEVM: Flashing sysbios uart code on tda3xevm

Thanks Rishabh , I will look into it and get back to you

Sorry , Can you please tell, where the loopback examples present in vision sdk. We are new to sysbios platform.

Thanks Rishabh for the great support,

Currently I'm trying to compile the uart example with some modifications using the command

UInt32 tempFuncPtr;
BspOsal_InitParams_t bspOsalInitPrms = {0};


BspUtils_uartInit();
tempFuncPtr = (UInt32) & BspUtils_uartPrint;
bspOsalInitPrms.printFxn = (BspOsal_PrintFxn) (tempFuncPtr);
BspOsal_Init(&bspOsalInitPrms);

I added the above code in uart examples and compiled using below command,

make -s bsp_examples_uart_echo BOARD=tda3xx-evm CORE=ipu1_0 BUILD_PROFILE=debug OS=linux

Changed the sysboot to uart and Flashed the big endian binaries using mflash utility, then changed the sysboot to qspi . But I didn't get any outputs from three uarts. But I got only SBL outputs from uart3.

Output

Hi Rishabh,

This app runs fine without problems,

Can you tell me what I'm doing wrong with bsp_uart example?

Hi,

if i understood correct, then Ti Rtos had the support to register the uart printf function with the below code,

UInt32 tempFuncPtr;
BspOsal_InitParams_t bspOsalInitPrms = {0};


BspUtils_uartInit();
tempFuncPtr = (UInt32) & BspUtils_uartPrint;
bspOsalInitPrms.printFxn = (BspOsal_PrintFxn) (tempFuncPtr);
BspOsal_Init(&bspOsalInitPrms);


Anyhow, what function needs to use for printing in uart?

Hi,

Can you tell how to change the uart in vps examples applications?
I tried to change in bspUtils_uart.c , but its not changing for us. So can you please guide us?

Hi,

Yes, we removed the scanf from the uart app and assigned the devid = 1 ; as well as devid=0; but nothing prints on uart0 and uart1.

Thank you very much for the support.
