Hi I used the instructions from the following link to write the 1.0B firmware on an Udoo Sense with 1.0A firmware. https://www.udoo.org/docs-blu/BLE_Firmware/Firmware_Update_(Serial).html The reason I did this was because the humidity brick wasn't working on this Udoo Blu Sense with 1.0A, but was working on a Udoo Blu with 1.0B (no Sense). After that, the udoo blu didn't start anymore, although I wrote back the 1.0A firmware and SmartRF Flash Programmer 2 v1.7.5 said both times that all the steps (erase, program, verify) were successful. Did I do anything wrong? I thought that, being the same chipset, the firmware should work, I just wouldn't have the code for Accelerometer & Magnetometer & Gyroscope. Is there any way to make it work again?
I have one working Udoo Blu left (no Sense), and from the Android app, using OTA, I successfully installed all 3 firmware types, so it's not a firmware issue. Also, I used this FTDI usb-serial adapter for Arduino Pro Mini multiple times, so also the serial adapter is good. I used this wiring for the connection between the serial adapter and Udoo Blu: https://www.udoo.org/docs-blu/img/blu_upload_serial_3.png So where is the mistake? Why the firmware update using a serial adapter is not working?
