Hello all, I have two questions regarding how to use pflash.1) I have two 64MiB flash devices, so do I use one "-pflash" on the command line that has an image that is the total size of both flashes or use two "-pflash" on the command line.
2) The parameters for the pflash register are a bit confusing. The block size for my device is 64 but that does not work, I currently have tested it with 128. Also, the sector value, I could not find that reference in the datasheet for my flash. How should I use it? I used 128 * 1024 and that worked too.
With the values I mentions above, I can mount the flash and us it as a root file system. I do get messages when I erase but I know that is not supported at the moment.
If someone can set me straight on #1 and #2 then I will have be submitting flash support for the Mainstone shortly.
TIA, Armin
