I2C error: i2c_dw_handle_tx_abort: lost arbitration

I'm working in a project to integrate a NFC device using a I2C interface. In the past, I was using this device without any problem in a Raspberry Pi 3 with the same I2C approach.

When I execute:

i2cdetect -y -r 5

There is no valid I/O address answer. I expect to obtain 0x24 as a valid I/O address.

I'm using this BIOS Setup:
• I2C Standard mode (100 Kbps)
• ACPI mode

The result for i2cdetect command in dmesg log was:

i2c_designware i2c_designware.1: i2c_dw_handle_tx_abort: lost arbitration

Someone can give me some advice?

Thanks in advance.
