S310 V2 bootloader hangs when calling softdevice

[Adib]

Hello,

I try to use the S310 V2 but got stuck into problems.

in order to start the application from bootloader in the S310 V1 I did succesfully :

void (*application)(void);
sd_softdevice_disable();
sd_softdevice_forward_to_application();
/* Jump to user application */
uint32_t application_pc = *(__IO uint32_t*)(application_start_address + 4);
application = (void (*)(void))application_pc;
/* Initialize user application's Stack Pointer */
__set_MSP(*(__IO uint32_t*) application_start_address);
application();

now in S310 V2 I replace the forward_to_application by the new command:

sd_softdevice_vector_table_base_set(application_start_address);

now even in the sd_softdevice_disable(); (as well as sd_softdevice_vector_table_base_set) the processor stucks in the SVC call. Initially I did not enable the sd. Do I have to do that? I am not using any service?

I checked also the reference here: devzone.nordicsemi.com/.../ but this was no help for me.

I programmed the softdevice using:

nrfjprog --programs softdevice.hex --dfu as well as
nrfjprog --programs softdevice.hex

but with no luck.

Thx for any help.

Regards, Adib.

There is a migration document located in the s310 download folder which explains the necessary steps for using SDK 6.1 with S310 V.2.0. You can also use the attached modified hrs example as reference. Or just place it directly in your SDK, then you only have to make sure to replace the API files in \nrf51422\Include\s310 with the new ones.
