Hi Christian, (...) you could add some code in lowlevel.c to dump the USB packets, and then look if you see anything wrong. Jürgen (17 years ago, 26-Jul-07, to lugnet.robotics.nxt.nxthacking)

(...) Hi Jürgen, very good idea. Please give me some hints where to start. I haven't found any --verbose command line parameters, yet :D OK, I'm trying to read the source again, expecting ENDIAN problems like every time using PPC and SPARC :-D Bye (...)

Hi NXT-Community, I'm searching for an alternate firmware flashing tool for the NXT... Using the Lego Mindstorms Software is an easy way to do this, but not available for my favorite operating systems. I've tried fwflash from libnxt, but without (...)

(...) So you have not removed the line from cCmdInitPool where VarsCmd.Pool is set equal to IOMapCmd.MemoryPool, correct? Can you say where "mem" comes from and is it for certain being initialized to zero or nil before cCmdInitPool gets called? Is (...) (17 years ago, 20-Jul-07, to lugnet.robotics.nxt.nxthacking)

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)

Starting with the original NXTGCC source, if I disable binsert in the makefile, the firmware crashes on boot. The firmware development which I am doing will probably increase the size of the firmware by around 20KB, so I'm wondering if I need to do (...)
