I would recommend reviewing the LoLo Users Manual - and when they are available the LoLo Labs. They cover part-add and mount which you will need to use to copy your image to flash. The info mem command will show you the locations of NoLo and LoLo and how many blocks you have on your device: losh> info mem Configuration of /dev/nand0: Total Blocks: 4096 Bytes Per Block: 135168 Has Chunks: yes Total Chunks: 262144 Chunks Per Block: 64 Bytes Per Chunk: 2112 Bytes Per Spare: 64 NoLo Partition: Block 0 /lboot Partition: Blocks 1 -> 17 Configuration of SDRAM: Base: 0x80000000 Size: 268435456 Configuration of SRAM_0: Base: 0x40200000 Size: 65536 LoLo RAM Usage: .text: 0x80000000 -> 0x8005bd1c .bss: 0x8005bd44 -> 0x8006407c Stack: 0x8006407c -> 0x8006707c Translation Table: 0x80068000 -> 0x80070000 Heap: 0x80070000 -> 0x80400000 Download buffer: 0x80800000 Loaded Image: None Heap Usage: Available: 3735296 Used: 92060 Free: 3643236 Maximum: 92340 Errors: 0 Boot Loader Files: LoLo: /lboot/lboot.elf losh> You can use the Ask A Question system for further assistance

I don't see them posted yet for the DM37. We have them for the OMAP 35, but it is possible some of the block numbers may have changed. Would you like me to send you a copy of the 35x ones? It may be enough to get you going. Thanks

As an alternative, you can load/burn the bootloader/kernel/fs by booting from the SD card first. Section 3.2.8 page 19 of the Linux BSP shows you how to do this.
