svc cause usagefault for porting nimble stack

[zhiqiang li]

Dear all,

I'm trying to run nimble stack with Nuttx  OS on nrf52832(pca10040) reference board. Now , most function is working , but it is not stable . 

Sometime , the svc call will cause usagefault exception , but my priority is all right configuration (svc is 0x00 , no other isr is higher than svc).

I'm not sure is there chip internal bug for the calling sequence ?  Thanks.

Regards,

Levin

Hello, we don't have any experience with nimble stack with Nuttx OS, but maybe someone else on the portal have.

I recommend that you may consider the FreeRTOS port in a recent SDK (e.g. \ble_app_hrs_freertos).
