No OTA consistency board to board on the same firmware/layout PCBA

[Chabose]

Hi, 

Recently, we have ordered PCBAs using nrf52832 to online PCB manufacturers.

During a test, we found that some boards can use OTA firmware update, but some are not.
We use the same software/softdevice/bootloader, but the results vary from board to board.

Logs are listed below for okay cases and ng cases. 

Does anyone have an idea what kind of factor affects the result of the OTA process?
Any suggestion will help.

## Device and Tools

• The device: nrf52832 EYSHCNZWZ(TAIYO YUDEN)
• SoftDevice: 15.3
• Software used for OTA: nrf connect(iOS)
• Bootloader: secure bootloader(based on secure_bootloader example)

## Logs

ok.txt - log from nrf connect the successful case

fail.txt - log from nrf connect the failed case

Thanks,

Hiroto

Hi,

Looks like the central device was not able to find the device(It should be advertising as "DfuTarg#your number after going into bootloader mode).

1)

Are you able to get the nrf_log output from the bootloader, either via UART or Segger RTT viewer as log backend? The _debug prefix projects have logging enabled. So use the pca10040_ble_debug secure_bootloader project. Maybe the log from the nRF52 might reveal something about why it's failing.

2) Do you see this issue when testing with different phones as well?

Hi Sigurd,

I do appreciate the instructions you've given.
You literally saved my day.

As soon as I use debug bootloader, I found I left LED code for nrf52DK in "dfu_observer()" without modification.
And it was stacked on "nrf_gpio_cfg_output()".

After removing unnecessary codes, it works perfectly.
I'm now assuming variation between the board is due to a bad reflowing process that some pads are shorted.

Thank you sooo much.
