Christopher Collins commented on MYNEWT-756:
--------------------------------------------
This works for me on the nRF51dk. One possibility is that your device is
running out of mbufs. The mpstat command is actually quite mbuf-hungry because
it generates such a large response. Unfortunately, we need the mpstat command
to determine if this is the case!
Are you building with a reduced mbuf size or count? For the record, here is
the target I used:
{noformat}
targets/bleprph-nrf51dk
app=apps/bleprph
bsp=hw/bsp/nrf51dk
build_profile=optimized
syscfg=BLE_LL_CFG_FEAT_LE_ENCRYPTION=0:BLE_PUBLIC_DEV_ADDR=(uint8_t[6]){0x1c,
0x22, 0x00, 0x99, 0x99,
0x99}:BLE_SM_LEGACY=0:BLE_SM_SC=0:LOG_LEVEL=1:STATS_NAMES=1
{noformat}
And here is the mpstat output:
