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
Hi Rogerio,
rogerio said: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:

Thus you can enlarge the linux kernel up to 5.3MB.
rogerio said:2) Size of uncompressed OS in the RAM
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

Pavel
