It will copy from the flash to DDR2 then pass execution to DDR2. It is simple copy
which does not have the facility to copy to different addresses.

Mike,
how does the bootloader work? If my code stored in FLASH is linked such that part of should be located in L1 or L2, does the bootloader just ignore it or does it somehow put everything in the DDR2 memory?
Thanks.

Mike,
So then I just need to change the bootargs to use ttyS2 instead of ttyS1 and the linux kernel console will be directed out uart2? At this point I will leave uboot output on uart1. It is good to know it shouldn't be too hard to f...

Hi Scott,
For the kernel, you should only need to change the console argument in the bootargs (assuming the pinmux settings are ok for the other serial port) to point at ttyS2.
For u-boot, if you mess it up, you can recover using t...

Hello,
We are using a MItyDSDPL138 with the MityDSP baseboard. We want to use uart1 on the baseboard to interface with a serial device and redirect console output through uart2. I will need to change the console in both uBoot and in t...

Is the DSP going to be communicating to the ARM via DSPLINK? If so, this may be a challenge as the ARM and DSP need to do some handshaking on startup after the linux kernel is loaded and initialized. You'll need to look closely at opti... Michael Williamson
