Implemented in app_trace.c:166

Arguments

Argument

Description

dest

Indicates HW interface to read the data on.

data

Address of buffer to put data from trace buffer.

size

Pointer to store size of read data. Before call to this function pointed memory must hold requested size of data

tmo

Timeout for operation (in us). Use ESP_APPTRACE_TMO_INFINITE to wait indefinitely.

Return value
