FlexBus CS pins and accessing unallocated memory space 1301 4
Started by ghlavenka@usbiometrics.com
I have the feeling this is really a simple question, but it's a hurdle I have to get over...
We've bought a couple of the Logic eval kits (FireEngine/ITX) to do development on. I want to hang a bytewide parallel device onto a CF processor; for the sake of discussion let's say it's a Hitachi character LCD.
Looking at the ITX board schematics, I see that the PC104 connectors have FlexBus signals on them, including 3 FBCS lines. I decide I want to generate FBCS3 for my LCD.
I cleaned the sold...

M5474LITE PCI INTA connected to IRQ7? 1447 3
Started by aaronjstewart@gmail.com
Hi - we've started working with the PCI slot on this board, only to realize that PCI INTA is tied to IRQ7. From what I can tell, IRQ7 is an NMI, and is not configurable in the interrupt controller. This would imply that I can never mask interrupts generated from my PCI card, which will cause problems in our OS which needs to disable all interrupts during certain sections of the code. Assuming my interpretation of IRQ7 is correct, I either need to run my PCI card in polling mode (not use the INTA...

Boot-up sequence 1372 7
Started by cbaron@nordson.com
In my past applications at boot-up the loader(not LoLo or BoLo) looks for a character at the serial port. If the character is seen the loader executes
commands to transfered a program file from a PC and burn to flash. If no character is seen the loader then jumps to a progarm location in flash. Since BoLo is gone, is there a way to reproduce the above steps using LoLo scripts

Can't build the Metrowerks BSP kernel 1330 9
Started by rnotari@curtisswright.com
I am trying to build the Metrowerks MCF547x 2.4 kernel (non pcs) under cygwin running under Windows XP. The first 2 steps seems to go ok ('make fresh', 'make config-m547xlite'). The third step ('make dep') runs for about 2 minutes and crashes with a 'too many arguements' error. Does anyone have any experience with this BSP version Please don't answer with a lot on UNIX techno-babble. I have never seen UNIX before, so all this is brand new to me.

I convert the elf file to raw with objcopy and I can move it any where in boot flash (0xFF80-0000) with LoLo's load and burn commands and at the dBug prompt type go <addr> and it runs fine.
As soon as I move it to user flash (0xE000-0000) and type go <addr> the dBug hangs. I've tried changing my memory map without success.
Also using exec or jump from LoLo hangs LoLo as well, regardless ...
