Hi TI engineer

I use I2C driver read BL24C64 a page data every second. when read start , it can get correct data.After 10 min or 30 min ,the I2C error I2C_STATUS_INCOMPLETE. When cc3235 restart ,read i2c data correct.

What causes this problem？

Can you check the same use case (reading the same amount of bytes in the same frequency) toward another device (e.g toward a CC3235SF in a slave mode)?

We are not familiar with a similar issue and suspect it is related to the BL24C64.

Can you capture (with logic analyzer) the I2C clock and data lines?

Thanks for reply!

I found this problem by hardware interference.
