Inconsistent whoAMI address of LSM6dsv320x on eval kit mk 1251

[rv_08]

I have bought a new eval board from semikart via aquatronics. The device mounted on dil 24 of mk1251 kit is lsm6dsv320. The whoamI address of the device is 0x73 but it was not coming when we integrate with nucleo board. So, I waited for eval kit IKS4A1 to double check which I had ordered on coming of eval mk1251. I got MEMS Studio running on a windows 11 machine. But when I opted for dil sensor lsm6dsv320 , it threw inconsistent whoAMI address error. I am trying to contact semikart and aquatronics from last 10 days but none of them are responding. kindly tell a way to correct it or replace the eval kit mk1251.

Hi @rv_08 ,

in X-NUCLEO-IKS4A1 is mounted a 6-axis device (LSM6DSO16IS) that respond to same I2C address (0xD4) of LSM6DSV320X but with different WhoAmI (0x22 instead of 0x73). To avoid this type of I2C address conflict, it is mandatory to follow what has been described in UM3239 chapter 3.6 (remove SB36 and SB38).

Thanks Federica Bossi. It worked. I saw the solution late. One more query - the unit hg in case of high g data selection in FSM is multiplied by 100 of that visible on MEMS Studio. ( When Simux uses high g data in place of low g)
