Uncomplete traces #19

Closed samiBendou closed 3 years ago

samiBendou commented 3 years ago

Current behavior:

Traces are not entirely printed via UART, end of the traces is missing
~ for a request of 16 traces => 4 ~ 6 traces with enough samples (>300)

Expected behavior

Traces are entirely printed
request n traces => 60% of the traces are correctly acquired

UART bytes communication:

Use Putty option All Session Output in Session > Login
Direct traces parsing from bytes (no ASCII conversion)
Improved parsing resilience

For hardware acquisition (500 samples/trace) Maximum chunk size before inconsistent reads occurs: 65536 (2^16) Maximum chunk size before memory overflow: 131072 (2^17)
