CC2340R5: Flash through bin

YW Lin

Part Number: CC2340R5
Other Parts Discussed in Thread: CC2640R2F, UNIFLASH

Hi TI members,

Below is my building environment:

Software	Version
Code Composer Studio	12.3.0.00005
SimpleLink SDK	7.10.00.35
XDCtools	3.62.1.16_core

We are working on migrating an old project from CC2640R2F to CC2340R5.

I could build our new CC2340R5 project which is based on the basic_ble example project.

I would like to transform the .hex file to bin file, and I've done this using a hex2bin function in python (from GitHub - deeplyembeddedWP/cc2640r2f-sbl-linux: A cc26x0 serial bootloader for linux).

Our old project of CC2640R2F used this python function to transform hex to bin successfully and the bin can be flashed to device using UniFlash.

However, I tried this with CC2340R5's hex, and flashed the bin with UniFlash, and it showed:

I wonder why this couldn't work for CC2340R5?

Thanks.

Hi,

Is there a reason you want to changed the hex to a bin file. You should be able to flash the Hex file straight from uniflash as well.

Kind Regards,

Hi,

In our previous CC2640R2F project, I saw our resigned colleagues had the hex file transformed to bin file.

The bin file could then be flashed on CC2640R2F using UART without the need of XDS110.

Please help to check the issue.

Thanks.

HI YW,

This is possible with the cc2340 as well, you would have to keep in consideration that the ccfg file has been updated to have permission to flash the device and debug.

Hi,

The problem was the generated bin file for CC2340R5 was about 1.2GB, while the hex file was only about 200KB.

We thought the generated bin file or the procedure of generating it might be wrong.

Please provide us how to correctly generate a bin file using hex file from TI's point of view.

Thanks.

Hello,

Other than following what the previous colleagues implementation is there a particular reason you want to use a bin file, are you using OAD? If not I would recommend you stick with the hex file. Another thing is the size seems way to big, for example the basic ble project hex file is only around 400 KB.

Kind Regards,

Hi,

We will still be using bin file since there has been a stable way of flashing it. So asking why are we using bin rather than hex will not help resolve our problem.

And 200MB was a typo, I apologize for this. It should be 200 KB, so I think our hex file is normal.

The problem is generating bin file, please focus on this issue. I feel like you are justing sidetracking us...

Please just provide us with the way to generate one bin file equivalent to hex.

2. I saw you mention "you would have to keep in consideration that the ccfg file has been updated to have permission to flash the device and debug."

How can we check if our CCFG has the permission to flash or not ?

Please provide methods for this.

Thanks.

Hello,

Yes 200 KB seems a lot more reasonable.

Just so we can be on the same page, your previous example was flashed using the serial bootloader?

Using Uniflash you can read the registers
