CC2652R: Problem with off chip BIM

As I mentioned in https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/158/t/825080 I'm trying to reflash a CC2652R with a zb image stored in an external flash received via UART from a CC3200.

I've generated an oad image to store in CC2652R internal flash, the .zigbee image to reflash with this commands:

Then I flashed CC2652R with off_chip_bim and the oad app generated in the previous step with uniflash as shown in next image:

The linker script I used for my app is the same as in zed_sw_ota_client example. Linker Script:

I'm able to store the .zigbee image in the external flash as i receive it from UART, but when i restar the cc2652 in order to execute bim portion of code(I use

SysCtrlSystemReset()) it doesn't work and the bim turns on red light(bim is in debug mode).

To be honest, I'm really lost with this problem. Is there any steps I'm missing or doing wrong? What further tests can I carry out? 

Thanks in advance,

Matias
