AN2295 for MC9S08AW32

oskaratk — Mon, 04 Apr 2011 11:17:26 GMT

hi .. I am fairly new to the world of microchips, so please excuse all my questions.

Managed to my app working using PeMicro Multilink ... however

now I am trying to figure how AN2295 bootloader works with a MC9S08AW32 MCU. Trying to use single wire

Into the AN2295 docu, the only reference to this MCU I am finding in Table 2, so I assume I have to use FC protocol V3.

But when I load the project hc08sprg-s08aw.mcp from the S08AW folder .. that is using FC protocol V2.

I have compiled loaded aboutve project and flashed.

running hc08sprg com1 9600 mys19.s19, after a powerdown reset, I am getting :

Waiting for HC(s)08 reset ACK ... received 0xdc (good)

Calibration break pulse sent. Count: ....

seem to be stuch in that loop counting.

I seem to see the break at RDX1 of the MCU

Any help is highly appreciated

Thanks

Oskar

well, I found my problem:

BEWARE of some USB to serial converters/cables.

Using a PC with a real RS232 port helped ... then I found a working USB-Serial cable too ...

Now the bootloader works just out of the box
