zephyr question

Hsu, Hanyu <Hanyu.Hsu@...>
 

Hi Sir,

 

We occurred some question when we use zephyr in nRF52832.

 

We found there were some chips cannot boot-up w/ Zephyr sample code (disable UART), but can boot up well w/ Nordic original sample code (ble_app_hrs).

But if we enabled the UART function of Zephyr sample code, the failure chip can boot up well.

 

Below is our test environment and procedure.

 

1.    We use zephyr sample 'peripheral_hr'  to test and the result as below.

For attached file,

- peripheral_hr_uart: The board configuration of PCA10040 in Zephy.

- peripheral_hr_no_uart: The board configuration of Nordic PCA1004. Disable UART through “menuconfig”

 

2.    For the block in red, we dump the debug information of back trace through J-link.

 

3.     Test procedure of Zephyr:

a.      Download and install zephyr SDK and zephyr ( http://docs.zephyrproject.org/1.8.0/getting_started/getting_started.html)

b.      Enter samples/bluetooth/peripheral_hr

c.       Create the firmware of peripheral_hr: make BOARD=nrf52_pca10040 -> It’s the firmware of “peripheral_hr_uart” (w/ UART).

d.      Create the firmware of “peripheral_hr” that remove UART: procedure as below.

          1) make BOARD=nrf52_pca10040  menuconfig

2) Disable ‘Console drivers', 'Serial Drivers': Enter path “Device Drivers”

          3) make BOARD=nrf52_pca10040 -> for the firmware of “peripheral_hr_no_uart”

 

NO
