QG8 Bootloader, not executing the relocated ISRs

FC — Tue, 10 Oct 2006 11:27:25 GMT

How would you explain not running the reloacted ISRs when using the bootloader? For example, I switched on and off leds in the test program within the ISR. I am trying to use FREEMaster software to debug the downloaded prgram via a SCI, no data, since the relocated SCI ISRs are not running.

Thanks

Hi,

thanks a lot for pointing this bug out. The QG bootloader hasn't been tested well FPROT/NVPROT allocation was wrong.

It should be like this:

NVPROT_ROM: SECTION
MY_NVPROT DC.B %11111100 ; flash protected (from 0xFE00)

For some lazy RS232 hardware (with long startup) I've added optional delay before any FC ack is sent out. If you uncomment it, the behaviour e.g. on QG8 demoboard improves.

Attached you can find the corrected version of the QG bootloader (also the software SCI version, suitable if standard SCI pins are not avilable or if single-wire communication is required, single-wire version has not been tested though).

This version will go to official AN2295SW quickly.

Regards, Pavel ok2ucx
