Thanks to everyone for their responses. Looks like building the /dev tree was not the problem. The ram size was the problem. I kept reducing the size from 96MB in the dd command and it finally worked at 16MB. Worked: ======= dd if=/dev/zero of=/dev1/dev/ram1 bs=1024 count=16000 16000+0 records in 16000+0 records out dd if=/dev/zero of=/dev1/dev/ram1 bs=1024 count=16384 16384+0 records in 16384+0 records out Fails if count is 16385 or greater: ===================================== dd if=/dev/zero of=/dev1/dev/ram1 bs=1024 count=16385 dd: writing `/dev1/dev/ram1': No space left on device 16385+0 records in 16384+0 records out Questions: 1. How can I check the ramsize? (I am on RHEL 4) 2. How can I increase it to be 96MB? 3. Should I post this as a new thread? Thanks! On 1/9/07, Supriya Sriraman <sriraman.supriya@xxxxxxxxx> wrote:
Dynamic detection and building of /dev tree will not work for me, unfortunately! This /dev tree is intended to be loaded on an embedded system that has Debian. I am building a debian linux system on RedHat (RHEL 4) and loading it on the embedded box. That is why I am trying to simulate the /dev tree that I will need on the target Debian box. Is there a way I can do this? I made a /dev1/dev and created a tree. Will that work? The dd command failed, so there must be something I am missing or doing wrong.
