Sorry, I think I was hasty in my reply. This would not work. We have the lmb_push()/lmb_get() functions only for the lmb specific tests. In this scenario, we have the load command which checks the lmb address against reservations, which are the "normal operation" memory map. So, if we have to have this to work, this might need a way of using a new lmb structure instance for every test. So that every test that gets invoked, does so like the way the lmb tests are. -sughosh > > -sughosh > > > > > If it becomes more widespread and affects a lot of tests, we could do > > thing automatically in the test framework, but for now, that doesn't > > seem necessary. > > > > > > > > -sughosh > > > > > > [1] - https://lists.denx.de/pipermail/u-boot/2024-July/560569.html > > > > Regards, > > Simon
