#148339 - LPC9XX bootload in production code |
I have been looking for this for a few days now.
Does the LPC9xx bootloads as it comes programed from the factory have a timeout that it waits for 'U' before jumping to 0x0000? I managed to use start900.a51 code from keil. I unfortunatly had the bootloader set to '0' and not '1'. Before I have to unsolder another chip (I am using the serial port only, no breaks) I would like to know what happens when I set the bootstat and watchdog to true. Will the bootloader wait 400ms for a possible download character 'U' then transfer control to 0x000 for the user code to operate? Thanks for any help, JD |
