i2c read Error getting data: Connection timed out

ShrithiR — Mon, 16 Sep 2024 07:00:54 GMT

Hii team,

We are using an i.MX8QM processor. We are using an i2C slave and reading some values using it. Sometimes we will encounter an issue like 'Error receiving data: connection timed out'.

After capturing the i2c read with the Logic analyzer, we understood that the master was sending 0 bit for reading. So we are experiencing a timeout issue.

Working condition LA capture:

Non Working condition LA capture:

Do you have any understanding of this? I would appreciate it if you could suggest a solution for this.

Thanks,
Shrithi

Hi @ShrithiR

Which i2c are you using? Can you capture signals as close to the soc as possible?

Best Regards
Zhiming

Hii,

Thank you for the reply.

This issue got solved. Some timing synchronization issue was there in i2c slave.
