CC2642R: CC2642R JTAG Programming

Hello,

I will ask one of our experts to comment on this post. It might take us couple of days to get back as it's a holiday on Monday.

Thanks,

Hi,

See, osal_snv_write() and osal_snv_read() at the documentation. Can you provide more details of your end application. Do you use simple peripheral as base for your testing?

Hi!

Can you tell where to find osal_snv_write() and osal_snv_read() in the documentation?

In the SimpleLink CC26x2 SDK there are functions NVS_read, NVS_write and NVS_erase.

What's the difference? What do I have to use?

My application is a LPC microprocessor programming the CC2642R1F via JTAG. So I'm implementing low level JTAG routines to transfer a monitor program running on CC2642R which then should give me functions to erase, read and write the flash memory.

What I'm figuring out is how to transfer the monitor code and then run it.
I think this is the easy part, because in the CC2642R it's based on ARM CortexM.
But what I don't understand so far is how to read, write and erase the flash.
I have no sufficient information from the TI website and I have links to the SDK which is massive which I don't know how to use at the moment.

What's the best way to go? Is there a detailed documentation about the flash functions?

I do not know exactly what you mean with "Do you use simple peripheral as base for your testing?"
Do you mean peripherals on my LPC (yes, JTAG is implemented via GPIO) or peripherals on the CC2642R?

Hi,

Refer to osal_snv_write() and osal_snv_read() from this link. Go to Developing a Bluetooth Low Energy Application -> Memory Managment-> Flash-> OSAL SNV

I am not sure what you meant by  "LPC microprocessor programming the CC2642R1F via JTAG". Does that mean you are not using IDE such as Code Composer Studio or IAR Embedded Workbench?

Hi,

I would highly recommend you to use the ROM bootloader instead of the JTAG interface for this. The BL functions are described in the Technical Reference Manual.

If you mean the serial bootloader this won't help me.

I have no choice, the use of the JTAG interface is a must.

My solution: Once I have transferred a monitor program to the chip then I will use the library functions suggested in the SDK for IAR.

Can you elaborate on why the serial bootloader is not an option? 

Our customer has layouted his PCBs only with a JTAG interface and has instructed us to use it.
There is no way for me to get around this.

From what I know BLE device will not pass BLE Qualification without UART interface. BLE tester send HCI commands through UART interface. So, maybe redesign is needed with UART interface.
