Linux/AM3351: Processor Linux SDK footprint

Part Number: AM3351


Tool/software: Linux

Question from customer:

1)    Size of compressed Linux in the External flash

2)    Size of uncompressed OS  in the RAM

3)    Size of BSP package. - for this one they can get the info here: http://software-dl.ti.com/processor-sdk-linux/esd/AM335X/latest/index_FDS.html

    1)    Size of compressed Linux in the External flash

    The default compressed Linux (zImage) in AM335x PSDK3.2 is 3.5MB. And the default NAND flash layout allocate 5.3MB space for the linux kernel:

    http://processors.wiki.ti.com/index.php/AM335x_U-Boot_User's_Guide#NAND_Layout

    Thus you can enlarge the linux kernel up to 5.3MB.

    The default compressed Linux (zImage) in AM335x PSDK3.2 is 3.5MB, while default uncompressed Linux (Image) is 10MB.

    See also the below pointers:

    zImage        - Compressed kernel image (arch/arm/boot/zImage) : 3.5MB (3470720 bytes)

    Image         - Uncompressed kernel image (arch/arm/boot/Image) : 10MB

    uImage        - U-Boot wrapped zImage : 3.5MB  (3470784 bytes)

    vmlinux      - kernel with the appropriate debug symbols : 13.5MB
