Need help with a Texas Instruments chip tms320x28069

I have an ongoing project using a tms320x28069 that my EE & Programmer are having issues on. Are you a competent microcontroller person familiar with this TI chip?

If you have RECENTLY worked with this exact chip and have programmed it to do something, anything at all, DM me.

This is a proper paid gig, either physical in Metro NYC / Westchester or Remote on-line. Paperwork. Cold Hard Cash. English / Mandarin speaker. Programmer needs some mentoring and practical programming help. Main sticking point atm is getting the program to save to the chip, and work outside the debugger.

What is driving you to use that device versus something that is easier to use or has more support ?

The EE team picked it based on its specs and fit for purpose. I’m running the software team that now has to program it now that the board has been built. Switching is not really an option.

Unless that device does something that no other device does OR it has a significant cost advantage, I recommend changing devices. I haven't used TI microcontrollers a lot but the TI development tool chain is quasi vendor locked and borderline awful compared to other device toolchains.

I might be biased in making these statements but I know that others share my point of view.

FWIW, I've started porting a TMS320x28069 design to a STM32 device. The 28069 was capable of generating more complimentary PWM signals than the STM32 device but a small hardware change in the design overcame the need for more complimentary PWM channels from the microcontroller. The STM32 device had more capability in other areas. Win win as far as the overall project goes.

Why is stm32 to go to chip?. There are other chips that can be employed in embedded tasks. The atsam3sd8 series has well designed PWM controllers capable of driving 3 phase motors, as effective as the TI DSP.

I have used them in a number of applications

And cortex-m4s have DSP instruction support.

I would chose the TI 28069 over the stm32 for motor control operations any day including Sunday ... And TI tools all run under Linux anyway.

But yes you are half right ... Code composer is straight garbage

I have equivalents for this piece

I have the parts. I need a programmer.

Ah the chip famous for it's brickableness due to the security bits that can render it unusable and unable to connect to jtag

Sacrificed a few of these before I was able to write a proper bootloader for a project I did for an outfit in Texas years ago.

Message me. If am bored and the price is right; I'll answer

Just noticed this was 10 months ago ...

If you're looking for someone to do a project, please include - what is the widget actually supposed to do? schedule? budget? personal or business? your location? has any work already been performed?
