Unable to boot with ADXL345 connected to SPI1 #103

I am having install/boot issues with my adxl345 on my Manta M8P +CB1 V1.0

I am unable to boot with the ADXL345 sensor attached to SPI1. Interestingly enough, if I hot plug the sensor into the SPI after a boot then everything works. I can successfully execute ACCELEROMETER_QUERY, AND MEASURE_AXES_NOISE. However, if I leave the sensor plugged in, I cannot boot.

The error I get when attempting to boot with the ADXL attached is: Lost communication with MCU 'mcu' Here is my setup in config:

[adxl345] cs_pin: PB15 spi_bus: spi1

MP8 pin adxl pin gnd gnd +5V vcc PA5 SCl PA6 SDO PB15 CS PA7 SDA

Lots of troubleshooting through the BTT Facebook group, but still no resolution. I have also tried wiring the ADXL into the Pi pins and software SPI but nothing has allowed me to boot with the ADXL connected.

Same issue here.

If ADXL345 connected on start, not boot. But if connect ADXL345 after boot complete, work correctly. ADXL345 -> Power source connected - not boot. ADXL345 -> Power source unconnected - boot ok -> ADXL345 hot plug work well
