Hi, I try to run Hard Hat Linux from Montavista as described in the CDK 1.2 manual on an RPX lite board. Unfortunately, the installation procedure is only for hosts with Red Hat Linux, I hoped this would work for SuSE, too. The problem has to do with the NFS filesystem. I can successfully

Hi All, I'm having trouble with compiling some code that I will use for our embedded system when booting the system. The function that I'm having trouble with is the printf function. I used this function in i386 and mips environement (cross compiling) and it worked fine, the argumenents are

Hi Jari, thank for your fast answer. I examined the problem I little bit further, maybe you find something, that can help me further with this new piece of information. you should see if you have the link sbin - bin in the target dir or not.. bash-2.03# dir -l total 100 drwxr-xr-x 2 root

I believe I have seen the same problem. As I recall, we first started seeing this problem when we removed a symlink (/opt/hardhat/devkit to /) that was included in the MontaVista target directory. We were told that we had it add it back because some of the MontaVista libraries were built

PCMCIA have machine check

Hello Jerry, We had a similar problem with our design. The PCMCIA_WAIT signal was stuck low. However since you are a comercial board I doubt that this is the case, but you might want to look at it anyway. My gut instinct tells me you may have some more work to do in

PCMCIA have machine check

You probably have the old RPX bootloader. It sets the Bus Montior timeout which causes machine checks for every IO operation. Contact EP tech support and request PlanetCore, the new bootloader. Nguyen Xuan Hoang wrote: Hi, I am trying to run Wireless Lan PCMCIA on RPXLite board, but the

you really should contact MV support for this kind of stuff (if you have a support contract). Ot is something with your basic setup. Did you add the /opt.../target directory to /etc/exports ? if so, did you restart the nfs server? is the nfs server running? Nils Hagge wrote: Hi, I try to

vxhack and mvista kernel

Hi. I am trying to use VxWorks boot rom to boot MontaVista's 2.4.0-test2 kernel on a EST SBC8260 board. I already have MontaVista's CDK 1.2 installed on a Linux x86 host running Red Hat 6.2. From a previous post I find that I'll need to hack the kernel zImage with Dan Malek's vxhack.c program. So
