Hello Everyone,
I'm new to this list and thought I would post a question. We are developing a FLASH-based board based on Micrel's KSZ9692 SOC that will run Linux version 2.6.23.17. Our desire is to be able to load a new Linux/rootfs image via TFTP for testing without overwriting the current kernel/rootfs stored in FLASH.
My original thought was to write a script using environmental variables. The script would look for a mImage on a server and load it if it is there. If we don't want to load an experimental linux/rootfs mImage, we would simply do not have the file present on the server, and the script would proceed to the next command having not found the file on the server. However, when it gets to that point in the code, it continues to retry over and over, and never gets past the 'File not Found' error.
I looked in the README file and found the variable CONFIG_NET_RETRY_COUNT and it seems to be set in a lot of files. However, if this variable applies to this, the script just ignores it and continues.
Does this parameter apply to this situation? If not, what section of code would I add/change to include this? Not having modified Uboot, the task seems to be daunting. How would I begin? Where would I start?
Thanks a lot!
Regards,
Rick
