PERIPHERAL INTERFACE ALERT MESSAGE FOR DOWNSTREAM DEVICE
First Claim
Patent Images
1. A method comprising:
- receiving an upstream message generated by a downstream device, wherein the upstream message is received via a peripheral interface of an upstream device and does not require a response; and
sending an alert message from the upstream device to the downstream device via the peripheral interface indicating that the received upstream message is corrupted by an error, such that the downstream device can generate;
debug information in response to the alert message, anddirectly output the debug information associated with the error for debugging the error.

Abstract
According to some embodiments, a message generated by a downstream device is received at upstream device. The message may, for example, be received via a peripheral interface and may not require a response. It may then be determined that an error is associated with the message, and an alert message may be sent from the upstream device to the downstream device via the peripheral interface.
