CC1310 and CC2640 flash programming via JTAG port

Other Parts Discussed in Thread: CC1310, CC2640

I’m writing from Lynxar Technologies, a professional ISP tools provider.

I need to support CC1310 and CC2640 microcontrollers.

A TI customer is waiting us to set up a professional system for the ISP programming on such devices.

The CC1310 and CC2640 interface (port) to be used must be JTAG (no SPI or bootloader).

I carefully studied the SWCU117F Technical Reference Manual, especially the chapter 5 section 5.2 and 5.2.1.

On those sections JTAG commands are described, but none of them is for the Flash programming.

There must be another document I can’t find with JTAG commands for PROGRAMMINGFLASH VIA JTAG PORT.

To sum up:

On SWCU117F Technical Reference Manual, some JTAG commands are mentioned, but none is dedicated to Flash Programming (Debug port).

For example:

1) Which are the registers used for Flash Programming (write enable, busy, etc.)?

2) Does the Flash access take place through a TAP?

3) If so, which one?

4) Otherwise, is Cortex M3 DAP involved? Which address? Which bus width (32-/64-bit)?

SWCU117F Technical Reference Manual do not mention any of the above questions.

I'd like to thank in advance anybody that can help me. My customer (an important TI customer is in need to program huge quantity of CCxxxx) is waiting for this.

Hi,

The documentation of this is unfortunately not good. I have attached some additional info for you.

Flash programming is done by the target CPU (using functions in ROM). The host loads a flashloader image into SRAM that runs these ROM functions. The data to be programmed is loaded by host into SRAM (via CPU_DAP). Host then runs the CPU for it to program the data in SRAM into flash. It's a 32bit system.

Let me know if you have further questions.

Thank you TIABO,

The information you attached is useful, but my R&D manager said there is still something missing.

I'll let you know details of what is still unclear. Meanwhile, should you find more information on the topic, I'd be grateful.

Let me know, thanks again.

Michael

Let me know what exactly is unclear and I will try to find the information for you.

Hi,

could somebody provide the document "CC13xx_CC26xx programming implementation.msg" as a PDF. I am interested in this matter but can not open files of type MSG.

Thanks in advance,

Alois.

Hi,

Uploading PDF variant of the zip.

Hi,

I am also looking at in-circuit programming the CC1310 over the cJTAG link.

Is there any further information on what cJTAG commands are required for the process described above?

More specifically, how do we access the SRAM (over cJTAG) in order to load in the flashloader and application images? I don't understand how we can read/write to the SRAM despite reading through the TRM (chapter 5).

Thanks,

We don't have any additional documentation available, but the cJTAG specification document (IEEE 1149.7) is perhaps a place to start.

This is a common question for advanced users, those of us that deal in the tens of thousands of devices. I recommend that Ti build a little MSP430 project that can program a Chameleon part over JTAG using an MSP430. I picked MSP430 because this is like a lowest common denominator; anyone can then take the project and run with it.

Any reason you would use a MSP430 as debugger when the Launchpads has one? For production you would typically use tools from a third party that is made for mass production.

In production many times we want to make our own programmer so we can program in parallel, to make things faster.

As I commented, for production I would recommend looking into 3. party tools, see processors.wiki.ti.com/.../CC13xx_CC26xx_Tools_Overview as some examples.

You no longer need to make your own programmer in order to speed-up programming.

Lynxar Technologies (www.lynxartech.com, info@lynxartech.com), the leading supplier for ISP programming, now support all CCxxxx families.

Lynxar flagship product, DeviceClip, is a fast and modular platform that allows you to parallel ISP program in unlimited number of target simultaneously.
