CC1352P: can I change BIM_VER macro at oad off-chip examples ?

Michael Brutman

Part Number: CC1352P

in the bim_offchip_CC1352P_4_LAUNCHXL_nortos_ticlang example , at oad_image_header.h I saw the following macro and warning:

/*!
 * Version of BIM this image is intended to work with
 *
 * \warning This is not intended to be changed
 */
#define BIM_VER                      0x3

is it possible to change the bim version? or it may lead to unexpected behavior somewhere in the code of oad?

Hi Michael,

what do you want to achieve by changing the BIM version?

Here is some information about that header: https://dev.ti.com/tirex/explore/content/simplelink_cc13xx_cc26xx_sdk_6_30_01_03/docs/ble5stack/ble_user_guide/html/oad-secure/image-header.html#bim-version

Arthur

I made some SW modifications into the bim project (I had to turn of a CS spi line of one of the DIO).

so I would like to differentiate between two versions of BIM hex files I use.

Hi,

It seems like BIM_VER is only ever used in bin_offchip_main.c:402/990, and in zcl_ota.c:956, when checking the image header.

So as long as you keep your track of your different version numbers, it should be fine.

Arthur
