Hello, I have a memory alignment problem with DFU as of now. mtdparts is as below device nand0 <fsl_nfc>, # parts = 4 #: name size offset mask_flags 0: vf-bcb 0x00020000 0x00000000 1 1: u-boot 0x00160000 0x00020000 1 2: u-boot-env 0x00080000 0x00180000 0 3: ubi 0x3fe00000 0x00200000 0 active partition: nand0,0 - (vf-bcb) 0x00020000 @ 0x00000000 defaults: mtdids : nand0=fsl_nfc mtdparts: mtdparts=fsl_nfc:128k(vf-bcb)ro,1408k(u-boot)ro,512k(u-boot-env),-(ubi) As per the above, setenv dfu_alt_info "vf-bcb part 0,1;u-boot part 0,2;ubi part 0,4" and CONFIG_SYS_CACHELINE_SIZE is 32. I have a ubifs image and i was trying to write it by running "dfu 0 nand 4" in u-boot and "sudo dfu-util -D ubifs.img -a ubi" on the host. I got the error as below. "dfu_get_buf: Could not memalign 0x800000 bytes Setting CONFIG_SYS_DFU_DATA_BUF_SIZE to (1024*1024) resolved this. After this, trying an update as above, did not give me an updated ubi (which i check by booting to user space) and doing a nand erase.part on ubi partition and then repeating the procedure results in ""Bad Linux ARM zImage magic!". After looking a bit online, at the below two links http://lists.denx.de/pipermail/u-boot/2013-May/155089.html http://www.linux-mtd.infradead.org/faq/ubifs.html#L_mkfubifs I started trying ubinize. Getting the memory alignment issues again now :). I have tried 1, 2, 4 and 8Mb for the dfu data buffer size. So i am trying to figure this out at the moment. I am probably missing something. :) --Best Regards, Sanchayan. > >> >> Thanks again for your inputs.
