I'm working on a custom firmware with a new VM. I'm currently trying to reuse the NXT-G memory pool to hold data for the new VM, but I'm running into problems. Apparently, doing a memset to set all of the pool to 0x00 causes the firmware to crash. (...) (17 years ago, 16-Jul-07, to lugnet.robotics.nxt.nxthacking)
