flash programmer can't write more than 200 byte at once

Contributor I

Hi everybody,

I've configured CW Flash Programmer Tool to Program/Erase my Spansion S29GL256P flash memory through PowerQuicc MPC8248. I'm using a USB TAP emulator. I've written a target initiaization file to configure the RAM and all was working fine when erasing and programming single or few (4-10) sectors. But since I erased all the flash memory (included the PowerQuicc bootloader) I can no longer program more than 200 byte in a single operation. This makes flash programming a very long operation.


Any suggestion?


I can only think that now PowerQuicc no longer boots at start up but this should not cause trouble if I connect with the JTAG in debug mode...
