Hi

Would you please advise if there is a Linux solution for the CY7C65215A Errata 5 - I2C Reads are slower when USB-Serial is configured as I2C Master?

The workaround provided lists a windows solution only.

Hi Malcolm,

Slower I2C reads in Windows was due to delay introduced in library API implementation Refer to this thread for more details - https://community.cypress.com/t5/USB-Low-Full-High-Speed/CY7C65211-USB-Serial-SDK-Long-delays-betwee...

I2C Read API in library for Linux does not contain any such delays and should work without issues. Can you please test this at your end and let me know if you find similar delay in Linux?

Best regards,
Pranava
