CCS/PGA900: PGA900: Programming PGA900

Part Number: PGA900
Other Parts Discussed in Thread: UNIFLASH, USB2ANY

Tool/software: Code Composer Studio

I want OTP to PGA900 with Uniflash which includes PGA900 support.
And I have a USB JTAG emulator (XDS200).
I modify the file(pga900.gel) to load the program to the correct memory space by modifying the config remap function:

Config_Remap()
{
WR_MEM_08(REMAP_ADDR,0x01);
}

Above is the original. Simply change it to what is shown below:

Config_Remap()
{
WR_MEM_08(REMAP_ADDR,0x01);
}

Then , The error occur as follow:

Hi Chennangan,

That's my mistake with the gel file. The two examples shown are actually the same. The modified file should read:

Config_Remap()
{
WR_MEM_08(REMAP_ADDR,0x00);
}

However the error seems to be related to something else. Have you set the proper target configuration settings for the XDS200 with the PGA900 in Uniflash? Please check the Connection Properties Parameter Configuration table from the PGA900 software quickstart guide (http://www.ti.com/lit/ml/sldu015a/sldu015a.pdf) to make sure you have everything set correctly.

Hi Scott:

I have do as the PGA900 software quickstart guide (http://www.ti.com/lit/ml/sldu015a/sldu015a.pdf) describe.

But It do’t work；

So what can I try to clear the question;

Hi Chennangan,

Additionally, you may need to reset the PGA900 through uniflash before beginning the programming. You can access the "Reset Actions" from the Uniflash utility to allow you to reset the PGA900, or you may have to manually power cycle the device.

But the problem is still.

Hi Chennangan,

It seems like it's some sort of JTAG connectivity issue. Please see this wiki that describes some debugging procedures you can try: http://software-dl.ti.com/ccs/esd/documents/ccsv7_debugging_jtag_connectivity_issues.html#Cannot_access_the_DAP

Also note, if you have programmed the OTP of the PGA900 already, you may not be able to connect to it.

Hi,Scott:

You means i can't connect to PGA900 both OTP and DERAM when i have programed the otp ?

Now, I can still do well on debug with a USB JTAG emulator (XDS200).

Hi Chennangan,

It depends on how you have programmed the OTP. If you haven't disabled any access in your firmware, then it should be fine.

Hi,Scott:

since I have done all of this. I change my tools XDS200 to USB2ANY;

I click the button of "VERIFY OTP",after this the button turn green as the follow picture;

But the error appears,when I click the button of " LOAD OTP Memory";

It's seems something wrony with my hex file;

But the file can do well whith debug with XDS200 on DEVROM;

So what can i do?

Hello Chennangan,

Do you click the Verify OTP before loading OTP through the USB2ANY? The verify OTP function is used to check the OTP data against the HEX file that you programmed. If you haven't put anything in the OTP yet, the function is not useful.

Is your firmware based on the example firmware from the PGA900 product page on ti.com? If not, you may need to make some changes to some of the build settings to ensure you get a usable hex file. First, I recommend checking the project properties for your firmware and specifically looking at the ARM Linker -> ARM Hex utility page. It should look like what is shown below:

Also, please make sure your processor options are set as shown below:

These are the settings needed for CCS.
