5485 PCI failure 1714 6
Started by kamilgrig
Hi,
We are using Zoom CDK MCF5485 board together with Freescale’s Linux Board Support Package ltib-mcf547x_8x-20051213.iso, based on kernel 2.6.10.
Our project is actually in final stage, but we faced a problem with PCI communication. Our device makes reading information from PCI our device and transferring it through TCP/IP to host PC.
The handshaking with PCI device is very simple. As soon as new device’s buffer is ready, the device pulls interrupt line down. We are using IRQ7 line for this ...

Performance. Coldfire vs ARM Is this as good as it gets? 1971 1

Hello All,
A colleague runs the included c program on his ARM system and gets times around 3.6 seconds. On my logicpd development board I'm getting about 16s. I know there are lots of variables here but I'm hoping to get an idea from the group as to whether we should expect more from the coldfire or not.
Thanks

M5485CFE: LoLo issues on watchdog reboot? 1505 1
Started by burelllil
Hello,
I am trying to debug an issue I get when the 5485 reboots due to the watchdog expiring. &91I know this should never happen, but that's another matter...).
We are using the latest Logic LinuxBSP and LoLo 2.0.6. The problem is that sometimes the uC reboots but hangs before entering (or inside) LoLo, as no messages are output by the serial port (I have a boot script in the E2PROM starting with VOLO so that normally I see what's going on). Notes:
- I'm sure the micro reboots, because outpu...

M5484LITE Kernel Panic 1665 6

Hey all,
Just got the M5484lite and built the m5484gfe-lite-romfs image for it. When I load the kernel it goes through, decompresses the romfs image and attempts to boot and it claims it cannot find init and the kernel panics. I have no other coldfire hardware to ensure busybox or bash built correctly (using logic's toolchain that I also built myself). Any ideas

I am a principal engineer that is presently tasked with developing a next generation instrument platform within my company. Since I am leaning towards using the Freescale 5474 running a Linux OS, I decided to buy the evaluator board. Needless to say, this has not been a very rewarding experience.
Problem 1: It is very confusing who exactly is responsible for the Linux build image. Freescale has instructions posted on their website for this board and Logic has theirs. Needless to say Frees...

I recently purchased an MCF5474Lite evaluation board from freescale. Using teraterm I could enter dbug just fine. After I set my baud rates, I tried to access LoLo, but when I typed 'go ff840000' the board just hung there not doing anything. I reset the board and tried again and same thing happened. When I did a memory display of ff840000 it looked as if the old LoLo was loaded, version 1.5. I uploaded version 2.0.5 as directed by application note 257, yet LoLo would still not come up. Tod...

GDB/BDM support under Cygwin for PCI parallel cards 1608 1

The GNU Cross Toolchain does not work for computers with non standard parallel ports. Since PCI parallel cards do not use the standard port addresses, GDB is not able to find the BDM device. In the "BUGS" file of the m68k-bdm-1.3.0 source folder, it says "- PCI parallel ports with non-standard port-addresses not supported.". Does this mean that GDB/BDM will not work on computers with PCI parallel cards at all Or do we have to edit the source code ourselves to make it wor...
