UART BIOS not working, C6748 platform

Hi George,

Before building the project, I request you to directly check/run the default binaries that come with the psp_01_30_01. When this succeeds, we can confirm that the GEL file and the hardware configurations are appropriate. Then, we can proceed further. Also verify other peripherals on your evm board. Let me know the results..

Best Regards,

Raghavendra

Dear Raghavendra,

Thanks for the reply, how do I check/run the default binaries that come with the psp_01_30_01?

Hi George,

After installing the PSP_01_30_01, run the binaries(already available) placed in - pspdrivers_01_30_01\packages\ti\pspiom\examples\evm6748\uart\interrupt\bin\Debug

Best regards,

Raghavendra

Hi Raghavendra,

I've run (run T.I. debugger->connect to target->load program)  the .out from the location you've specified but nothing happened, the problem still exists. In the user manual for UART it states that the program when run it will output the following string to the Uart ouput channel: “UART Demo Starts: INPUT a file of size 1000 bytes".

However, the example shows running but nothing is seen on the console screen. In addition, when I hit go to main (Target->go to main) again nothing happens the cursor does not seem to go to main, although within the Target tab the "goto main" option is masked, so CCS seems to think that the program has jumped at main?

In general because I've tested the ethernet example (with the same gel) and it works, I was expecting also with the UART after the gel runs the program to wait at main, just as it is done with the ethernet. But this hasn't happened with the UART example and I can't figure out if the problem lies at the program itself or if it is a CCS configuration problem.

I think I've followed all the required steps, but if you have a procedure that I can follow from scratch to theoretically set the UART to work (a procedure that has been tested elsewhere) I can make a new project and test it to find out if I'm missing any steps during configuraton, etc.

thanks,

George.

Hi George,

Please share the GEL file you are using. Also, you are checking the output on a hyperterminal or a teraterm?. There is no extra configuration to be made. The default binaries are tested and should work as is on the EVM. You are using a C6748 EVM or a custom EVM(modified)?. Please try loading/running other peripheral binaries(like i2c, spi, etc) and check.

Let me know..

Best Regards,

Raghavendra

Hi Raghavendra,

I'm checking the output on Terminal v1.9b (by bray++). I've tested the pc and the nul cable with a loop around and it works. I am using a C6748 custom board, and I'm selecting the ti.platforms.evm6748 from the Tools menu which is the closest to my board. It is the same platform I've selected when I got the ethernet example to work.

I've also tried other peripherals like I2C and USB but the problem persists.

As I see it the main question here is, why the example(s) do not display their output on the console (or on the ROV) as the psp manual describes? The tool I'm using to check the UART is not relevant  at the moment because the examples does not even get to the point where they display their output. For example the i2c should display: Start of I2C sample application, the UART should show: "UART Demo Starts: INPUT a file of size 1000 bytes", etc.

I have attached the gel file for your info (converted it to .txt as I wasn't able to attach it otherwise)

Thanks again,

George.

Hello to All,

I managed to place breakpoints in the code (I'm running the uartSample in debug mode). The code doesn't seem to pass from main (I have active breakpoints there) and it goes directly to the: " user_uart2_init()" function and it seems to stop there. I assume this because it stops at my breakpoint in this function and then when I click on run again it shows running but it doesn't get to any of the other functions: genericUartTest() or echo(), I have also put breakpoints there to check, but the code doen't seem to go anywhere else besides the  " user_uart2_init()" within the: "uartSample.c".

any thoughts? anyone?

Hi George,

Sorry for the delayed response..

I do not find the GEL file attached?. Also, if you are using a custom board, understand the differences between your board and the EVM. Accordingly, you will have to modify the sample applications. For example, in the pspdrivers_01_30_01 the UART sample application uses UART instance 2 to perform read/write wherein, the output is seen on the UART console (Hyperterminal PC, baudrate- 115200) connected to the DB9 connectors on the EVM. Are you testing UART 2 instance itself on your custom board?. If it is a different instance of UART, you will have to change the sample application by changing the device id(uartSample.tci) and do the PINMUX appropriately(platforms/evm6748/src/uart_evmInit.c).

George Paravas said:

The code doesn't seem to pass from main (I have active breakpoints there) and it goes directly to the: " user_uart2_init()" function and it seems to stop there.

The echo() task(refer uartSample.tcf) is called after the static creation of the uart device. For this to be successful make sure the above settings/configurations is done appropriately. Still if you do not succeed try probing(placing breapoint) in the uart driver(Uart_init(), uartMdBindDev() ) reload and check.

 All the sample applications in the psp_01_30_01 uses "LOG_printf()" print messages and these are not directly viewed on the CCSv4 console. For this, you will have to check the CCSv4 userguide. In CCSv3.3, goto tools->DSP/BIOS->message log to view the print messages. 

Hope this helps..

Hi Ragavendra, Thanks for the info,

I've checked the schematic of the board and the port I'm connected to (DB9) is connected to UART2 on the C6748. I guess this means that I'm using UART instance 2?

Also is there a manual/schematic of the EVM 6748 so I can check the differences of that board with ours?

About the ccs4 messages, they show on the ROV , under LOG.

So if I understand it correctly after the UART gets created and configured, uartSample.tcf calls the echo task to connect to the port and wait for data ta come in and then echo them back?

Also when I run the application, under ROV->LOG I see the following:

LOG_system

seqnum 0:

TSK: ready TSK_idle (0x11825ca4)

seqnum 1:

TSK: ready echoTask (0x11825d04)

Since attaching does not work I'm copying the gel file below, I'll appreciate it if you can give it a quick look.

(let me know when you have it so I can delete it, to save some space in this blog)

Thanks again.

Hi George,

George Paravas said:

So if I understand it correctly after the UART gets created and configured, uartSample.tcf calls the echo task to connect to the port and wait for data ta come in and then echo them back?

Yes, Thats correct. It outputs "UART Demo Starts:  INPUT a file of size 1000 bytes" on the Hyperterminal/teraterm and then you will have to send a file of 1000 bytes(sample.txt) which will be echoed back on the Hyperterminal/teraterm.

I have copied the GEL file data you posted(can remove it now!) and the main difference I see is in setting the PLLM multilplier. Please find the GEL file attached(C6748.txt) and try using this one and check the UART's behavior (Since it does not allow attaching *.gel file, I have coverted it to *.txt). When composing a post, there are 3 options - compose | options | preview . By clicking options, you can attach/upload the files.

seqnum 1:

TSK: ready echoTask (0x11825d04)

So, is it going inside echoTask?

Did you try probing into the UART driver?. Is there any progress here? Let me know..

Best Regards,

Raghavendra
