AM263P4: Bare-metal startup code

Tool/software:

Hello.

Is there any possibility to create empty project with startup code, linker script, main functions (may be also system clock configuration) etc?

I can create working project with SysConfig, but it always creates RTI instance with interrupt, debug console, UART module and so on, which are not needed for me (and also waste MCU time and block some module, which I want to use by my own)?

May be you have some example on MCU initialization for bare-metal project?

Hello Ivan,

The MCU+SDK contains an "Empty" example projects. However, this still configures RTI/Debug/UART-console/etc. You will need to take a final step and remove those minimal configuration options to get as close to the bare-metal example you want to achieve. Providing link the Empty Example documentation below. The actual example can be found at:

\...\mcu_plus_sdk_am263px_xx_xx_xx_xx\examples\empty

https://software-dl.ti.com/mcu-plus-sdk/esd/AM263PX/latest/exports/docs/api_guide_am263px/EXAMPLES_EMPTY.html

Hope this helps get you started. Please feel free to follow up with additional questions as they arise.

Best Regards,

Remove configuration options is blocked, and I cannot find any dependencies for it.

Hi Ivan,

You can remove the UART module by manually editing the example.syscfg file in a text editor and remove the below section:

Where as RTI module is added for system ticks for interrupts so it would be needed.You can read more about the clock ticks here: software-dl.ti.com/.../KERNEL_DPL_CLOCK_PAGE.html

Hi. Thanks, I can try to remove all manually.

Actually that is what I'm trying to do. I do not need system ticks, as I don't want to use Kernel DPL. My goal is to get valid startup code only.
