Hello @CarlosAM_INTEL,

We recently acquired the Intel® Core™ i7-7600U Processor directly from the OEM. Initially, it performed without any issues. However, over the past two months, we've encountered a problem. When attempting to export pins, we're encountering a write error.

We'd appreciate your assistance in resolving this matter promptly.

Thank you,

Manjunathreddy.
