I have a SM bus device running at 100KHz but otherwise the same as an I2C device - is there a way to slow the I2C bus down to be able to use this device?
Hi Chris
this is possible, depending on used part: for i.MX8M one can change
clock frequency in CCM (sect.5.1 Clock Control Module (CCM)),
Table 5-1. Clock Root Table i.MX8MDQ Reference Manual
https://www.nxp.com/docs/en/reference-manual/IMX8MDQLQRM.pdf
For i.MX8QM, QX parts using SCFW SCFW Porting Kit
Best regards
igor
