RTOS/TDA2P-ACD: Building appImage for pdk package

Hi Prasad,

Have you connected two EVMs as given in processors.wiki.ti.com/.../PDK_TDA_CSL_User_Guide
Also as you are running the app using SBL you need to wait for SBL to finish. To do this you can add a 100 ms wait in the beginning of MCSPI application.

Hi Rishabh,

Thank you for your quick response.

I was trying to check whether the programs start or not by waiting to see any print messages on the console. But since no message was seen on console I felt it is not running.

I had given the board for taking lines out from the board as pin outs are not available. (Please consider providing some jumper connectors for gpios & other peripherals like spi, uart, etc. similar to your other SoC's evms).

I will run the mcspi_spi1tospi2 today again with hardware connections.

One update: when I ran the Led blinking example, I can see leds blinking.

So, that means applications are running properly but System_printf() outputs are not redirected to terminal via uart.

Can you tell me how to do this?

Regards,
Prasad

Hi Prasad,

Led blink app is working fine.
System_printf is not routed to UART. You should use Vps_printf.

Rishabh

Hi Rishabh,

Since Vps_printf is in vision sdk (vision_sdk/links_fw/src/rtos/utils_common/src/utils_remote_log_server.c), when I compile mcspi_loopback example with System_printf replaced by Vps_printf, I get compilation termination error.

Please help on how to resolve this.

Prasad

Hi Prasad,

Sorry I did not understand that you want to use prints in BSP example.
Can you see if GT_0trace works for you.

Regards,
Rishabh

Hi Rishabh,

I tried with GT_0trace(as shown below), but it didn't work:
void spiSampleTask(UArg arg1, UArg arg2)
{
Task_sleep(1000U);
GT_0trace(BspAppTrace, GT_ERR, "spiSampleTask started!!!\n");

Also, I tried with Bsp_printf() & uartStdio(present in <pdk>/packages/ti/drv/stw_lld/uartconsole/src/uartStdio.c) but nothing gets printed on the console.

However, Uart Echo Example(present at <pdk>/packages/ti/drv/bsp_lld/uart/examples/uart_echo) works.

Please tell me how to proceed.

Prasad

Hi Prasad,

Sorry for the delayed response.
Can you try running the DSS example i.e. vps_examples_displayDss using SBL.
This application has UART prints. Let's confirm if that works for you.

Rishabh

Hi Rishabh,

With vps_examples_displayDSS, I can see some messages. Following is the console log:-

waiting for 1 min to load buffer from scripting consolePress any key (in UART console) after loading buffer

This confirms uart prints via SBL works.
If I'm not wrong, starting log (till "Putting MPU in Retention...") itself confirms that uart prints via SBL works.

Should I try with printing via SBL or any other approach do you suggest?

Hi,

We haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).

Rishabh

Hi Rishabh,

Sorry for the delay.

I am busy with few other things, so was not able to check this.
Also, in the mean time, I got access to debugger. So, was not blocked on this.

I will update about this as soon as I test this.

Thank you for your support till now.

Regards,
Prasad
