CC2640R2F: Hex and binary file are too LARGE to be programmed into CC2640R2F(SDK v1.50.00.58)

Part Number: CC2640R2F
Other Parts Discussed in Thread: SIMPLELINK-CC2640R2-SDK

Hi TI,

Now I'm using the CC2640R2F SDK v1.50.00.58, and the problem is that, hex and binary files are too LARGE to be programmed into CC2640R2F.

The .hex file is 790KB, and the .bin file is 281KB(Both of them include Stack and App). It causes that I cannot use SmartRF Flash Programmer 2(v1.7.5) to program my CC2640R2F.

However, before this, I used the CC2640R2F SDK v1.30.00.25, the .hex files were 199KB(App file) and 83KB(Stack File), only 282KB totally, dramatically less than 790KB, and they were successfully programmed into CC2640R2F.

Is there any method to shrink the .hex and the .bin files' volume, with the CC2640R2F SDK v1.50.00.58?

Thanks.

Which example do you build and do you modify anything?

Thank you for the reply.
I've been developing an own program based on the example named "Simple_Peripheral", and I added 3 services and the MPU9250 MPL. But I don't think it matters, because the Apps are the SAME. The only difference between them is the version of the CC2640R2F SDK.

Different SDK version would use different RAM/Flash. If you can build and download original example to your CC2640R2, it means Stack is fine. You should check how many of your application codes are added up to cause this trouble.

Thx. I'd give a try.

I've tried the TI original simplest "Simple_Peripheral" project and I've built it. However, the .bin file is still too large(171KB), and it still cannot be programmed into CC2640R2F. I wonder that if I've made any mistake on the project's options.

Hi,

Are you using CCS or IAR? Did you follow our guide section developing with CCS/IAR?

I suggest you to remove complete BLE Stack and reinstall it to test again.

Hi,

If you are using BLE5 example program, the stack is bigger compared to non-BLE5 example program.

Thx.
I've checked it again. The example should be a BLE4.2 example program. Its build configuration is "FlashROM_StackLibrary", so it's an application build configuration linked to the Stack Library, fully executable.

Thanks for the suggestion, but removing the BLE Stack does not meet our company's request......We do need use BLE to control our CC2640R2F.

Yes, I'm using IAR 8.11.2. Now the problem is that, only IAR can program the project into CC2640R2F, while the SmartRF Flash Programmer 2 can't.
I do followed TI's guide section "Developing with IAR".

For removing BLE Stack, I mean to suggest you to reinstall a fresh new BLE Stack to do the test again.

Can you flash programmer 2 recognize CC2640R2F?

0 user4917449 over 7 years ago in reply to YiKai Chen

Intellectual 875 points

Yes, my cc2640R2F is recognized.

Then, what do you mean "only IAR can program the project into CC2640R2F, while the SmartRF Flash Programmer 2 can't?"

The SmartRF Flash Programmer 2 says that my .bin and .hex file is too large to program into CC2640R2F, but I really don't know how IAR can manage to shrink the program's volume. Now our company is about to outsourcing program it in batches, and the IAR should NOT be used, to keep our source code away from being pirated.

If you use CCS to build the hex file, does it work?

0 user4917449 over 7 years ago in reply to YiKai Chen

Intellectual 875 points

Thx. I'll try it again.

Did you manage to get it to work?

0 Christin Lee over 7 years ago in reply to user4917449

Hi,

If you get it to work, I would like to close this thread.

Please let us know if it still does not work.

Thank you all the same, though I've not get it to work to shrink the .bin file's volume...and, now I'm trying some new methods.

If the map file shows an erroneous range, then likely it's a project or linker configuration issue that is making it appear that the memory footprint is larger than it is. Supplying your resulting map file would help confirm.

More likely, it's probably an incorrect setting used to merge the hexfiles or generate the bin file, and the conversion tool is padding the output thus resulting in a bloated bin file.

Just to confirm, you are using the SIMPLELINK-CC2640R2-SDK and not the SIMPLELINK-CC26x2-SDK.

Since the map file and/or the full build logs are not supplied as an attachment, it's purely speculative.
