Hello everyone, a while ago I've bought a Mini2440 with 1GB NAND. I played around with it a bit. And I changed the bootloader from supervivi to u-boot. But after scrubbing the device the NAND size decreased from 1GB to 128MB. I am sure that it was 1GB NAND before the first scrub, since u-boot showed me the size the first time I tested it. But I used different u-boot versions for the first tests and for the first scrub, which happend a few days after the first test. I don't know why I did this stupid move, but it happend. Up until know I used different versions of u-boot from different sources (precompiled from FriendlyARM and other sites and self-compiled). I'm not sure anymore which version I used for scrubbing the NAND, since I scrubbed it againg and again, in order to try to repair the damage I did. I can't reproduce the screen output from u-boot but I can outline the steps I did take (first part mainly from http://code.google.com/p/mini2440/wiki/MiniBringup). 1. Switch to NOR and boot the device 2. Load u-boot into ram to any address (e.g. 0x31000000) with >>load ram 0x31000000 sizeOfUboot u<< 3. Execute u-boot with >>go 0x31000000<< 4. Stop the autoboot by hitting any key 5. Scrub the nand with >>nand scrub<< 6. Create bad block table: >>nand createbbt<< 7. Write u-boot from RAM to Nand: >>nand write.e 31000000 0 sizeOfUboot<< 8. Partition the NAND >>dynpart<< 9. Get the offset with >>mtdparts<< 9. Create the environement for u-boot: >>dynenv set u-boot-offset<< 10. Save it to NAND >>saveenv<< I can't recall how long the scrub process (step 5) did take, but I know that I didn't interrupt it. Further on I know that with the 10 steps from above I couldn't get u-boot into the device, so directly afterwards I tried the steps from Bill's Blog (http://bill.station51.net/index.php?post/2010/01/16/U-Boot-on-Mini2440). The last steps from the May update (bottom of the page): 1. Switch to NOR and hit >>v<< in supervivi 2. Upload the u-boot.bin file 3. Switch to nand and boot u-boot (here I noticed the decreased NAND size) 4. Scrub the NAND and create the 'bad block table' 5. Switch to NOR, hit >>v<< again and upload u-boot again 8. Switch back to NAND and boot up 9. Run >>dynpart<< and >>dynenv<< I suppose that I decreased the size of the NAND with the first scrub. The NAND itself works properly, I flashed it with several Linux distributions (e.g. Angstrom). The size restriction didn't disturb me at first, but now I want to install mono on it, and the cross compiled size of mono is to big for the 128MB. So my question is, if there is a way to increase the size again to 1GB? If so, what steps do I have to take? Kind regards Markus Schmidt P.S. please excuse my bad english, I'm no native speaker
