1 Replies and 1587 Views Using MCF547x Fire Engine on a PCI card  1587  1 Started by  Deleted User I was wondering if it was possible to use the Fire Engine module on a card plugged into the PCI bus of a standard Pentium 4 personal computer I notice that the MCF547x/8x series contain many of the PCI host support functions such as bus arbitration. Can these be disabled to that the PC's North Bridge arbiter and PCI support functions are used instead Are there any drivers available for the use of this board as a PCI add-on to a PC Thanks, James

7 Replies and 1631 Views GCC does not produce FPU code  1631  7 Started by  laslo Hello. I've been trying to compile some fpu code but gcc does not want to cooperate. If i use the -m5407 option then it compiles in soft fpu emulation, if i try to use -mcfv4e (i think that this should be the right target for fpu) then i get an error message cc1: error: invalid option 'cfv4e' after some investigation it seems that m68k-elf-as does support -mcfv4e but cc1 does not. Any sugestions Thanks in advance.

5 Replies and 1684 Views Can't access upper half of M5474LITEKIT 4MB Flash  1684  5 Started by  craigdry My M5474LITEKIT has a 4MB flash(Intel 28F320). I can only access the first 2MB. I believe this is due to an error in the Logic Schematic which shows A0-A20 being in use for a 4MB part. However the Intel 28F320 says that A0-A21 are required. I need a workaround. On my board R426 is open and R427 has a resistor. Should I remove the resistor or close R426 Thanks.

Here is the command I used to store the script into eeprom:“losh> echo “VOVOhelp dir; info mem; exit;” /dev/serial_eeprom”. I then used the “cat” to confirm the script. When I reboot the Fire Engine board all I see is the standard power-up messages. What is wrong with the script newuser
