Hi,All
I used the board customized by imx8mq and developed the code from imx8mq_evk.Encountered a problem: reboot when the i2c SDA pulled down after failed to restore the i2c lethal lock.
I observed the board of imx8mq_evk, and there was no reset pin of PTN5110.So how does it avoid this problem?Did you control the power?
thank you so mach~~
Hi dhty2015
could you try to reproduce issue on i.MX8M EVK reference board with Demo Images from
it should not lock as board was designed to remove power (voltage source) to all
components on the board in the event of a processor reset.
Best regards
igor

我现在在uboot中控制了与之相关的电源,复位时,会局部重上电。这样问题就解决了。
