Hi Maksim, I have done what you told me, but i have an error when copy my rootfs in mini2440. I have tried with [v] Download vivi [k] Download linux kernel [y] Download root_yaffs image usind u-boot,uImage and roofs.arm.jffs2 build by buildroot. I followed this procedure http://narnia.cs.ttu.edu/drupal/node/131. One time, I tried to use uImage_N35 and the results are these ones: RPC: Registered tcp transport module. lib80211: common routines for IEEE802.11 drivers s3c2410-rtc s3c2410-rtc: setting system clock to 2009-11-11 12:40:40 UTC (1257943240) VFS: Cannot open root device "mtdblock3" or unknown-block(31,3) Please append a correct "root=" boot option; here are the available partitions: 1f00 384 mtdblock0 (driver?) 1f01 2048 mtdblock1 (driver?) 1f02 63104 mtdblock2 (driver?) 1f03 65536 mtdblock3 (driver?) Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,3) While, if I use uImage, the same that they use in the http://narnia.cs.ttu.edu/drupal/node/131, I have: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x001dc018: 0x1a93 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x001dc01c: 0xbb62 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x001dc020: 0x7cbe instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x001dc024: 0x3cdf instead Further such events for this erase block will not be printed VFS: Mounted root (jffs2 filesystem) on device 31:3. Freeing init memory: 132K Kernel panic - not syncing: Attempted to kill init! Could you help me, please? Thank you
