Re: How can I make flash writeable?

Ok, so bear with me. I've read booting-without-of.txt in the =20 Documentation/powerpc directory and I modified a .dts file but now what? I use ltib or u-boot to load that into the device or do I roll a =20 kernel with that file and flash the device with it? Apologies for the less than technical questions. Quoting Marco Stornelli [off-list ref]:
Hi Mark,quoted
How can I tell which devices are mapped to /proc/mtd devices?If I well understand the question, you'd like to change the partitions layout (?), so you should check out the dts file to see the flash layout, then you can specify there the partitions and change the dimensions, if they are read-only...and so on.

I am using the MPC8313E-RDB and I am having some problems using the flash that comes on the board. Let me preface this by saying that I haven't worked in the embedded linux arena in about 10 years so I am trying to catch up with all the new toys. This board uses uBoot and it currently has 128M of DDR2, 8M flash and 32M NAND Flash. I have a few questions: How can I tell which memory device it uses to boot out of? How can I tell which devices are mapped to /proc/mtd devices? I want to create a writeable flash partition, is there a FAQ out there I could look at. All of this is after a few days of using Google to try and glean some data from the internet. And the books don't get here from Amazon until Monday. I would appreciate any help. Even a RTFM - if you could point me to TFM, it would greatly help. _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded-- Marco Stornelli Embedded Software Engineer CoRiTeL - Consorzio di Ricerca sulle Telecomunicazioni http://www.coritel.it marco.stornelli@coritel.it +39 06 72582838
