MCF5373L external flash programming

Hello, I have a problem. I'm using MCF5373 based custom board and I use the CodeWarrior Flash programmer tool to program the external flash. Everything works all right as long as the binary size stays below 0x6D00 (27904) bytes. Somehow I can't program bigger code into the flash (4M*16). I suspect, that the MCF5373 has 32k SRAM and the Flash programmer first wants to download the whole code into that SRAM and then would program the flash, but my code doesn't fit into the SRAM buffer.

So all in all, I can't program more than 0x6D00 bytes of data, because of the little SRAM of the device. Am I right? How can I circumwent this limitation?

TIA, Richard
