Android uart bootloader used python

[Jerry]

Hi,

   I used SDK_15.1.0, secure_bootloader/pca10040e_uart.

Through PC uart,it update successfully .But boot through android(linux) uart,it returned 'invalid crc'.Can anybody help me?Thanks!

Hi,

It should not matter if you use PC (with nrfutil) or Linux. Are you using the same .zip file in both cases? How do you do the upgrade from Linux? Can you upload exact descriptions of how you do it in both cases (show full nrfutil commands etc.)?

Hi,

Windows: nrfutil dfu serial -pkg F:\dfu_app_pkg.zip -fc 0 -p COM2

Linux:uartSecureDFU ttyMT1 ./dfu_app_pkg.zip

I have upgraded nRF52832 on PC and Linux,and it worked well.In order to reduce the cost,I used 52810,But It can't work.Thanks!

The former is the value you bootloader replied to me, and the latter is the value calculated by my local upgrade program, which is inconsistent.
