I tried to develop our own CompactFlash driver on MCF5485EvB, I have the CPLD code and I can successfully read out the CPLD hardware and software revision and signture. I can also read/write the CompactFlash ATA register but after I issue IDENTIFY DEVICE command, the data returned is not correct I could not find the CompactFlash signture there and other information, all the 512 bytes data contains the same data pattern.

Using MCF547x Fire Engine on a PCI card 1598 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

Xilinx Xc2C128 CPLD ... cannot program this device. WHY? 2218 3
Started by wmohat
I am trying to use the PC-104 interface on the FireEngine.
There are SERIOUS design flaws with this interface, which I have
corrected. And, I have produced timing diagrams, documentation,
and CPLD source code to make this interface functional.
HOWEVER----
I am not able to program the Xilinx CPLD on the board, which controls
many of I/O devices (like the Compact FLASH, etc) and the
PC-104 connector.
I have tried programming the XC2C128 CPLD, using both a

GCC does not produce FPU code 1644 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.

Exercising I2C from losh prompt 1662 3

Using information from pages 26-14 and 26-15 of Freescale's MCF547x Reference Manual (Rev 2.1) I issue the following commands to losh:

This should theoretically issue a STOP to all slaves and make sure the bus is idle.
At this point, I dump the registers to see what state everything's in:

Can't access upper half of M5474LITEKIT 4MB Flash 1694 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.

I would like my application stored in FLASH, but loaded to, and run from, RAM at boot-up. I know that “load” and “burn” can save the program into FLASH, but are there LOLO functions to unload the program from FLASH to RAM at boot-up time

Hi
I can’t seem to make a boot-time script work. 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
