Hi, I have successfully used the BHI360 shuttle board with an STM32 (through level converter). BHI360 seem to match our needs. I have therefore made a custom BHI360 board, but I cannot make it work (please find attached the schematics of the board) We are using SPI at low frequency (~2MHz) Some differences I have seen, between custom board vs shuttle board : - product_id = 0x80 instead of 0x89 before upload - boot_status = 0x10 instead of 0x18 after upload to ram - boot status = 0x3F instead of 0x38 bhy2_boot_from_ram fails with error BHY2_E_TIMEOUT firmware is BHI360_Turbo.fw.h I use BHY2_SensorAPI from github The BHI360 comes from reliable suppliers (mouser). Any idea that would explain why I cannot make standalone BHI360 work, but have no issue with the shuttle board ? I'm at a loss Thanks
