LeJOS NXJ 0.3 is out! After a long and painful delay (especially for the developers) the new and improved version of leJOS NXJ is finally available. This new version has many new features including storing programs and data to flash memory, a menu (...) (17 years ago, 17-Jul-07, to lugnet.robotics.nxt)

| | Messing with memory pool
|
|
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)

I use BrickOS (LegOS) but I'm not expert in the inner workings. The code you have here appears fine to me. So, it may be a bug in BrickOS, or a problem elsewhere in your code. I will say I've ran into some interesting things when using tasks. (...) (17 years ago, 16-Jul-07, to lugnet.robotics.rcx.legos)
