6 Replies and 1690 Views 5485 PCI failure  1690  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 ...

Coldfire vs ARM Is this as good as it gets?  1940  1 Started by  tbob 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.

1 Replies and 1476 Views M5485CFE: LoLo issues on watchdog reboot?  1476  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...

Now what I have noticed,in the BDM the PSTCLK is enable(Synchronous mode) and the PSTCLK is running at 133Mhz. Gdb doesnt seem to work on Asynchronous mode(PSTCLK disabled). However the logicPD user Manual documentation says otherwise. Now how can I make GDB work on both mode. We have developed our own board with 5485. We are having issue with the BDM. PSTCLK is at 100Mhz in our board. gdb-bdm doesnt se...

6 Replies and 1635 Views M5484LITE Kernel Panic  1635  6 Started by  piku 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 There is my kernel image build, the romfs image by itself and bash and busybox tarred up...

1 Replies and 1487 Views [M547xLITE] Debugging the Linux Kernel  1487  1 Started by  kwong Hi, I'm new to the Coldfire series and debugging via BDM. I'm currently having trouble debugging a Linux v2.6.10 kernel using BDM. I can't seem to properly step to the next statement in the kernel... everytime I try, I get the following error: BDM error: Target Bus Error Admittedly, my environment has some quirks to it that may be the cause.

5 Replies and 1643 Views 5474LITE Evaluation Problems  1643  5 Started by  gary.carlson 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...

After installing Cygwin and the GNU Cross Development Toolchain v2.4, I ran gdb and tried to open up the BDM device (by entering 'target bdm /dev/bdmcf0'. GDB returned an error saying 'BDM error: No such device'. The LPT port is set to 1 and I know that bdmcf0 corresponds to that.

22 Replies and 2683 Views Starting Lolo just outputs garbage.  2683  22 Started by  Andy Daytona
(Topic has multiple pages1 2 )
Hi, I have the 5475EVB rev B and I am trying to start lolo from dBug. I start it with the command go ff840000 Two LEDs on the board starts blinking alternately and I get garbage text in my terminal. It seems to understand what I am typing because different command give different amounts of garbage... I tried upgrading to the latest version on the Logic website but nothing changed so I suppose it was the latest version from the start. My terminal is set to 115200bps. dBug works fine at 11520...

1 Replies and 1477 Views LoLo will not start!!  1477  1 Started by  djr3203 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...

1 Replies and 1579 Views GDB/BDM support under Cygwin for PCI parallel cards  1579  1 Started by  vmo 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...

I wired in a Microchip 24LC256 eeprom and ran i2cdetect 0 in Linux and did not see the part at address 0x04 where I expected. I did see the rtc part at address 0x32. I was able to run i2cdump 0 0x32 and see the rtc registers without the 24LC256 wired in. I then tried to run i2cdump 0 0x32 with the 24LC256 wired in to J22, with no power, and now i2cdump 0 0x32 hangs, with or without the 24LC256 wired in ...
