To repair my lps node(replace the mcu)
Posted: Wed Apr 28, 2021 6:14 am
Hi, dear guys
Several months ago, i bought a set of LPS devices from SEED and it worked quite well.
Recently, for some operational reasons, one of the nodes did not work anymore. By detecting the hardware, i’d confirmed that the MCU is damaged. So i got some STM32F072CBT6 from Mouser and replaced the old one, downloaded the latest bootloader and firmware from github, programmed the chip with DFU.
When everything is done, the node can't work! Observing the leds, it seems that there's something wrong when switching from bootloader to firmware.
Can anyone tell me how to repair the node?
Codes on https://github.com/bitcraze/lps-node-bootloader can be used? Or i can only buy a new devices?
Thanks a lot.
