platform-titiva's Issues

WARNING: board/ek-tm4c123gxl.cfg is deprecated

I get the following OpenOCD error when attempting upload on the tm4c123 board. I've tried both the stable and development versions. Any workaround would be appreciated.

tool-openocd not being installed for upload

This package is not being automatically installed (when not present) when trying to upload to the TI LaunchPad (Tiva C) w/ tm4c123 (80MHz) - lptm4c1230c3pm - hence causing the upload to fail.

platform-titiva/platform.json

Lines 45 to 49 in a02b171

"tool-openocd": {
"type": "debugger",
"optional": true,
"version": "~2.1000.0"
}

with platformio.ini consisting of

[env:lptm4c1230c3pm]
platform = titiva
board = lptm4c1230c3pm
framework = energia

openocd is found after running platformio platform install titiva --with-package tool-openocd

Applies to stable and beta.

Forum reference: https://community.platformio.org/t/ti-launchpad-tiva-c-upload-error/8407

Upgrade Energia Version

Please can we upgrade Energia to at least 1.0.4 to address I2C bugs as discussed here: energia/tivac-core#41

I haven't been able to figure out how to do this exactly since the energia git repo obviously does not include a package.json file.

SRST Error & OpenOCD Warning

Hey yall,

I'm having a bit of an issue with flashing my TM4C123 board. The first is the warning from OpenOCD to switch to board/ti_ek-tm4c123gxl.cfg. Is there a way I can configure that in platformio? Or is that fixed in a newer release?

Second, I get a bunch of Error: SRST error but the board does get flashed. I can even launch the debugger and step through the code. Is this error something that can be easily fixed on my end?

Upload error using EK-TM4C123GXL evaluation board

I have been trying the Blink LED example (libopencm3). I have modified the platformio.ini in order to have only the lptm4c1230c3pmenv, i.e. this file only has

[env:lptm4c1230c3pm]
platform = titiva
framework = libopencm3
board = lptm4c1230c3pm

The project builds OK. When upload is executed, I get this output in terminal:

> Executing task in folder libopencm3-blink: platformio run --target upload --target monitor --environment lptm4c1230c3pm <

================================================================================= [FAILED] Took 1.31 seconds =================================================================================
The terminal process "platformio 'run', '--target', 'upload', '--target', 'monitor', '--environment', 'lptm4c1230c3pm'" terminated with exit code: 1.

Terminal will be reused by tasks, press any key to close it.

I don't known what the errors messages mean. The TM4C is flashed OK and the example program runs successfully (LED blinks on three colors).

Have I missed something? There is a workaround for this? Please let me know if you need something else. Thanks.

Compiling uses wrong linker script with libopencm3 framework

See thread: thread

This goes over my head, but when building, the compiler seems to be using the incorrect linker script. According to the board file, it should use

"ldscript": "lm4fcpp_blizzard.ld"

but in reality it uses:

"~/.platformio/packages/framework-libopencm3/lib/lm4f/libopencm3_lm4f.ld"

The issue is that libopencm3_lm4f.ld does not define memory regions. The compiler will build and upload the code, but the processor will go into a blocking handler and sit in a while(1) loop.

I fixed the issue by defining the memory regions in libopencm3_lm4f.ld.

I was told by PlatformIO's maxgerhardt to open an issue here.

undefined reference to `QEIFilterEnable'

HI.

I am using tm4c123 to develop a project with encoder function. I like to use platformIO very much. I chose the arduino framework in PlatformIO, but the compiler told me there was an error,

undefined reference to QEIFilterEnable

I checked the qei.h file and found that this function is not available, but my CCS IDE can compile normally,

I found that the driverlib version of platform-tiva is very low. I don't know whether the platform-tiva is still maintained. Can I upgrade the driverlib manually,
