March 8, 20233 yr Hello, I am trying to port my developed module to the newest Armbian system. Once I had everything worked in very old Armbian developed in 2018 based on kernel 3.4. There is a hardware module connected via i2c1. When my program tries to communicate with it, it doesn't work and I get errors kernel: i2c i2c-1: mv64xxx: I2C bus locked, block: 1, time_left: 0 I've uploaded the diagnosis information to URL: https://paste.armbian.com/aciwalafah There was a problem also in Armbian 22.11 system. I upgraded it after found information about some solution for i2c probem with similar error messages. Please advise. Thanks.
March 9, 20233 yr Author Hello, the issue was closed by some change in my program that uses i2c connection (used write() instead of i2c_smbus_write_quick() function). The fix was applied after I discovered that i2cdetect call works correctly until my program is activated. Hope this can help to somebody with similar problem.
