program size in Flash ROM

Other Parts Discussed in Thread: OMAPL138

Hey,

I'm new to the C6748 processor and not familiar with how big applications can be.  The C6748 evaluation board includes a 4 GB Flash ROM, which seems massive to me.  I've seen applications on other processors only require 10 Mbytes.  Could someone give me some example program sizes for various applications?

Thanks,

Tobyn VanVeghten

    Tobyn,

    I am assuming that you are referring to the LCDK evaluation platform. The LCDK platform as you may have noticed is available for both C6748(DSP only) and OMAPL138 (ARM+DSP) devices. On the ARM +DSP devices, users can boot high level OS on the device  like linux, qnx or winCE. On an ARM+DSP device, to boot an high level OS like requires space secondary bootloader (uboot), Kernel image and file system and in addition to the DSP application image which is why we choose to add a 4GB flash on the evaluation platform. 

    For DSP only devices, the images will seldom require that large amount of memory. Typically the image size would be in order of mega bytes. but you can use the additional space to store filter co-efficients, reference images, back up boot images, store system state for recovery etc.

    Regards,
