TMS320F280049C: Support Needed for Bootloader Configuration on TMS320F280049C-56RSH pin

Part Number: TMS320F280049C
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hello Sir,

We are using the TMS320F280049C-56RSH microcontroller. We have access to two GPIO pins:

GPIO12 – connected to both SCIB_TX & CANB_TX
GPIO13 – connected to both SCIB_RX & CANB_RX

We are using the flashapi_ex2_sci_kernel and flashapi_ex3_live_firmware_update example applications for SCI bootl oading. These examples are based on the 100-pin LaunchPad version of the F280049C, and they use SCIA by default.

Since the SysConfig tool is not available, we are manually configuring everything.

Following questions I have;

How can we change the SCI interface from SCIA to SCIB?
If we switch to SCIB, where in the code or libraries should we update the pin mappings and peripheral configuration?
How can we implement CAN bootloading?
Please guide us on how to modify the example codes (ex2 and ex3) to support CAN-based bootloading, using CANB through GPIO12 and GPIO13.

I hope to hear from you soon!!

With Regards,
Nibesh

Hi Nibesh,

All you would need to do is replace SCIA_BASE with SCIB_BASE everywhere in the software and reconfigure the pinmuxing for SCIB. The main difference between SCIA & SCIB is that on LaunchPADs and controlCARDs, only two specific SCIA pins are routed to the XDS110 and can show up on a PC serial port. It sounds like you are using a custom board though, so that wouldn't make a difference.

Best Regards,

Delaney

Thank You Delaney Woodward
Will you please help me to convert (ex2 and ex3) SCI Bootloader to CAN Bootloader.
If you have any useful datasheet, that will be ease for me.

Hi Nibesh,

I have looped in the CAN bootloader experts and then should get back to you with a response shortly.

Best Regards,

Hi Nibesh,

We have some CAN examples generated for some of our devices that you can refer to:

CAN Flash Programming of C2000 Microcontrollers

Thanks and regards,

Charles

Hi Charles,

We have already referred to the CAN Flash Programming datasheet.
We are currently working with the F280049C controller, and we are looking for guidance on converting the SCI bootloader to a CAN bootloader for this device.

I have also reviewed the MCAN functionality on the F28003x controller, which primarily supports a GPIO-based bootloader. However, as MCAN is not supported on the F280049C, we are seeking an alternative approach.

Could you please help us understand the process of converting the SCI bootloader to a CAN-based bootloader for the F280049C?

I hope to hear from you soon!

With Regards,
Nibesh

Hi Nibesh,

Can you clarify what exactly you are having issues with? To convert the SCI bootloader to a CAN-based bootloader, you will have to replace the peripheral configuration such that it configures CAN rather than SCI. Do you need assistance configuring CAN without Sysconfig?

Kind regards,

Skyler
