Hello,
I have developed a Zephyr BLE project with the MAX30102 sensor.
I tested the code successfully with the nRF52833 DK, and it works fine.
Now, I am trying to flash the code to my custom PCB (nRF52833-CJAA-B-R7) chip, However, it seems I cannot flash the merged.hex file using the J-FLASH V7.96i tool. I also tried using the nRF Connect Desktop app, but it didn't work.
However, I was able to test the custom PCB with a sample code using this package: https://github.com/h2zero/platform-n-able#1.0.0 This code turns on the sensor and advertises the device name.
I sent the code using the PlatformIO VS Code extension tool. I sent it directly to the external chip using the VS Code PlatformIO tool (P19 port). But when I try to flash the .hex file generated by this (https://github.com/h2zero/platform-n-able#1.0.0) code through the J-FLASH tool, it does not work.
I am not sure whether the issue is with chip detection (hardware) or if the .hex file is missing a library (e.g., SoftDevice).
Could you please advise me on what I might be missing here? Why is it not working for the other code?
