TM4C1231H6PGE: USB device mode configuration problems

Update: it seems like the issue might have to do with the hw_memmap #define USB0_BASE. I started commenting out some code where I was having the issue and once the code reaches a line with USB0_BASE it will die with a break address of 0x4aac4bac

Hello Micah,

TM4C1231H6PGE doesn't have a USB peripheral so that's why its causing an error.

USB peripherals are offered starting with TM4C1233 device so TM4C1233H6PGE would be the package equivalent with USB.

Best Regards,

Ralph Jacobi

Hi Ralph,

I made the change to the TM4C1233H6PGE package, but I am still having an issue when configuring USB although it is a little different than before. Now I can go through the steps to configure USB, however when my code continues to configure any other pin/peripheral I get the same error as before. Really it seems like now as soon as I am done configuring USB, as described above, any code that executes afterward ends up at this break address 0x4aac4bac.

Hello Micah,

I don't see a peripheral enable for USB0 peripheral before calling any USB APIs. Please add this right after the call for SYSCTL_PERIPH_GPIOL:

SysCtlPeripheralEnable(SYSCTL_PERIPH_USB0);

If that has already used in the code or the issue is still present after that adjustment, since the TM4C1233H6PGE only has Device Mode functionality, you may need to try using this instead:

USBStackModeSet(0, eUSBModeDevice, 0);

Force Mode is used mainly with devices with USB0ID and USB0VBUS that are used for Host Mode so perhaps using that is causing an issue where the stack is trying to access something not present on the device.

Best Regards,

Ralph Jacobi

Hi Ralph,

I added both of your recommended code changes, but the behavior still persists. The other thing that is strange is that while I am debugging if I try to step over any code after the USB configuration I end up at the 0x4aac4bac address, but if I continually step into that code it seems to execute fine. This way I am unable to see exactly where things are going wrong.

Hi Micah,

The behavior you mentioned is simply because the code is in the usblib.lib library file so the compile can't step into it.

What is your system clock settings?

Once I have that I will try and re-use your code on my LaunchPad to debug further.

Best Regards,

Ralph Jacobi

This is the only line of code I have for the system clock

SysCtlClockSet(SYSCTL_SYSDIV_4 | SYSCTL_USE_PLL | SYSCTL_OSC_MAIN | SYSCTL_XTAL_12MHZ);

I have been able to step into the usblib while debugging. It seems like things go off the rails once the usbdenum.c in function USBDCDINIT line 512 when attempting to enable the usb interrupt. 

//
// Enable the USB interrupt.
//
OS_INT_ENABLE(g_psDCDInst[0].ui32IntNum);

Hello Micah,

I suspect there is something larger that is going awry here. I made a very minimal configuration for USB and confirmed that the following code would execute:

    SysCtlClockSet(SYSCTL_SYSDIV_4 | SYSCTL_USE_PLL | SYSCTL_OSC_MAIN | SYSCTL_XTAL_25MHZ);

    SysCtlPeripheralEnable(SYSCTL_PERIPH_USB0);
    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOD);

    GPIOPinTypeUSBAnalog(GPIO_PORTD_BASE, GPIO_PIN_4);

    GPIOPinTypeUSBAnalog(GPIO_PORTD_BASE, GPIO_PIN_5);

    USBBufferInit(&g_sTxBuffer);
    USBBufferInit(&g_sRxBuffer);

    USBStackModeSet(0, eUSBModeDevice, 0);

    USBDCDCInit(0, &g_sCDCDevice);

Note I used different pins because the LaunchPad has the PM package instead.

The USB code itself had blank Rx/Tx/Control Handlers and I am not trying to connect to USB. Just prove out that those APIs without any further configurations would avoid program crashing.

So I suspect you either have the USB connection hooked up and so something is sending data in which is crashing the application, or you have some code that is being processed by the USB stack in one of your handlers that is causing the issue.

I would recommend you use this document to try and track down what is causing the problem: https://www.ti.com/lit/pdf/spma043

I will forward mention that there is a holiday for TI in the US tomorrow so I will have to review any further updates you have on this on Monday.

Ralph Jacobi

I think I may have found the issue, but in the process uncovered another issue. It looks like someone had commented out the .intvecs section. I commented them back in but now am getting this error.

"configPkg/linker.cmd", line 95: error #10099-D: program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section. placement with alignment fails for section ".bootVecs" size 0x8, overlaps with ".intvecs", size 0x26c (page 0)

both .bootVecs .intvecs are being defined to be at 0x00.  I have found that the memory location for .intvecs if being defined in my .cmd file, but the memory location for .bootVecs seems to be autogenerated in the linker.cmd file. So far I am unable to fix this issue.

Hi Micah,

That is very strange - I am not familiar with the bootVecs being used for TM4C devices. Can you post the full .cmd file here? Do you know which device was used as the basis for it? Maybe also check your .ccxml file to make sure the right TM4C is selected?

Best Regards,

Ralph Jacobi

Hi Ralph,

Here are both of those files. I have also tried to manually change the address of the .intvecs but I get an error that it doesnt line up with FLASH.

Hi Ralph,

So I have tried to trash that linker.cmd file. however everytime that I build the project it is generated again. I was doing some reading online and I think that linker.cmd file comes from the XDC tools. Do I actually need XDC tools? When I first set up this project I got an error that I needed to install XDC Tools, but doing some reading online it seems that XDC tools might only be needed when doing RTOS. My project is not RTOS, but I have not been able to exclude XDC tools without generating lots of errors.

Hi Micah,

Let me get our CCS team to help out with this - I am not sure how to solve that, but I am sure there is a way to resolve it.

Best Regards,

Ralph Jacobi

Can you share these errors? XDCTools is typically not needed unless the project is RTSC based and uses SYS/BIOS (Do you have *.cfg file in your project?)

Thanks

ki

I have 1 .cfg file in my root directory that is empty and several in the generated Debug folder.  Do you want me to send you any of those generated files? Here is the error that I have been getting once I try to remove XDC tools.

It sounds like the project was created as a RTSC project. Can you share the three .*project files in your project folder?

Also provide the *.cfg file

Thanks

ki

Here are all those files. As I mentioned above the .cfg file at my root is empty so I am omitting that but have included the .cfg files generated in the DEBUG folder

This project is configured for RTSC (which is BIOS / TI-RTOS based).

Did you create the project yourself or did you reuse an existing RTSC based project as a baseline?

To be honest I dont remember exactly. originally we had been using and NXP processor and were trying to make the switch to TI. I think when we did the switch to TI we set it up ourselves. I think we were following some online documentation to get everything set up. Is there an easy way to fix this issue?

If you do not plan on using any RTSC components, then you should use a non-RTSC project.

Micah Blauvelt said:

A project is auto-converted to a RTSC project when a RTSC .cfg is added to the project. A RTSC project will have a dependency on XDCTools.

Unfortunately you can not convert an existing RTSC project to a non-RTSC project, even if the .cfg file is removed (it is a one-way conversion only). It is recommended to create a new non-RTSC project from scratch.

I compared the .cproject file from the base example with the one in my project folder and got rid of all of the references to xdc and I am now able to compile just fine. This seems to work.

I am having another issue with ccs configuration. Ill post this here for now, but if you need me to start another discussion I can do that.

I have been running into an issue that once i merge mycode into a git repo then try to create a new branch all of the sudden theEnums are no longer recognized by ccs. The Enums are defined in a text file and are brought into theprogram via a #include statement. The thing that is strange is that it seems that ccs knows about the enums and the file that they are defined in, but it cant seem to link any use of the enums back to the definition. It had been working fine for days, but once we merged back into the repo I started getting the issue and the only way I could find to resolve it was to delete my metadata. I am guessing that there might be config file that I am not tracking and I was wondering if you might have an idea of where to look?

Hi Micah,

We recommend you make new threads for new issues that are not directly related to the prior one. You can also select CODECOMPOSER as a part number instead of your TM4C device to get the thread routed to our CCS experts immediately.

Best Regards,

Ralph Jacobi.
