A new problem on using OpenSourceBDM

Hi,

Several days ago, CrasyCat offers a new License.dat of "CW5.0 for 08 SE", then OpenSourceBDM can write FLASH of target MCU. Thanks a lot for CrazyCat.

Now, I happened a new problem on using OSBDM. My procedure is below:

1. Connect a MCU which has a blank FLASH to OSBDM; Run Hiwave 5.0 for 08;

2. "set gdi", then Hiwave can read target's FLASH, obviously, it's blank. And I can reset target too.

3. "Load...", I download a *.s19 file to target FLASH, it's OK! Then in Memory Window of Hiwave, we can read bytes in target FLASH. And, the target MCU can run correctly!

4. When I connect the above target MCU to OSBDM again, some error happened. I can't erase target MCU's FLASH, FLASH operation error message is "flash module is bad or protected."

5. Then I unsecure the target FLASH follow the "ReadMe_unsecure.txt" file. After several seconds, "Command Windows" show that "done,...". Maybe, the target have been unsecured. But, in fact, the "4. " error happened again...

So, is anyone can solve the problem? If my procedure is fault?

Thanks!

Hi Lemonmeng,

Sometimes the OSBDM seems to get out of whack or confused.

It then reads everthing as 0x00 and presumes it is secured.

I have found the command "Reset to Normal Mode" under the Open Souce BDM menu seems to get things going again.

I have tried using P&E software and a USB Multilink to secure the device then access the device with the OSBDM, it connects and shows 00's in the memory window and you get the error you find. Now running the unsecure cmd file will unsecure it. If its just gone screwy trying to unsecure it won't help.

Now I need to find a way to programme the security and the NV trim registers after I have flashed the device. I have tried modifying the unsecure cmd file but so far without success.

OK I figured it out now, forgot you can only prog a FLASH 1 to 0. duh!
