From abba76354a049c48fcdf4a252383ccd5c119b8ae Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Mon, 9 Jul 2018 19:16:26 +0200 Subject: [PATCH] test/py: return a RAM address different from 0 as it can be interpreted as NULL Some functions test that the given address is not NULL (0) and fail or have a different behaviour if that's the case (e.g. hexport_r). Let's make the RAM base address to be not zero by setting it to 2MiB if that's the case. 2MiB is chosen because it represents the size of an ARM LPAE/v8 section.
