Linux/LAUNCHXL-CC26X2R1: ti154stack_linux_x64_2_08_00_04--cc13xx-sbl

Tool/software: Linux

Hi,

I use the cc13xx-sbl from ti154stack_linux_x64_2_08_00_04 SDK under linux environment for downloading my firmware. But it failed when the download progress goes about 83%.

I add some simple debug messages for this issue and find out:

the while loop ended(it tests the condition and figure out file reached EOF) when download progress is at 83%,but the bytes in buffer is 12768 left as follows:

I can not find the wrong thing within the code.

By the way, why is the MAX buffer size 252 and whether I can adjust it to other number according something. (#define CCDNLD_MAX_BYTES_PER_TRANSFER 252)

my linux commandline cmd:

$ sudo chmod 777 /dev/ttyACM*

$ ./host_cc13xx-sbl /dev/ttyACM2 ble5_simple_peripheral_cc26x2r1lp_app.bin cc26x2 -e -p -v

Thanks.

Hello User,

Have you tried flashing other images?

The reason for this limit, is that this is the maximum amount of bytes able to be transferred in a single packet using the serial boot loader. Section 10.2.3 of the technical reference manual talks more in depth about this. www.ti.com/.../swcu185b.pdf

I would try another image while I run some tests.

Regards,
AB

Hi AB,

I have tried the .hex image file.

The program run and got the similar result(download progress goes 83% and failed. ) but a little different: control flow did not reach the verification and ccDnldStatus is 1:

Thanks.

Hi
AB suggest to flash other kind of image. Like Simple_Peripheral or Project_Zero.

Hi Jerry && AB,

I tried the Project Zero hex file just now. My command is:

$ ./host_cc13xx-sbl /dev/ttyACM2 ble5_project_zero_cc26x2r1lp_app_FlashROM_Release.hex cc26x2 -e -p -v

And the result is the same:83%.

Thanks,

Sam Xu

Hi AB && Jerry,

Thanks for your support.

I decided to use the .bin file for right now. The download process can be successful if using .bin file read from CC2652 LAUNCHXL.

Best Regards,

Sam Xu

After further investigation, within our team and resources. I would like to make clear that this tool only supports .bin files and not .hex files. Sorry for not catching this earlier.

Regadrs,
AB
