TWR-56F8257 Bootloader problem

danielbronson — Sun, 27 Jan 2013 05:09:44 GMT

Well, I jacked up my USB bootloader. The TWR-56F8257 tower board uses the MC9S08JM60CLD to do its OSBDM programming and to main processor: the MC56F8257.

I tried to update the MC9S08JM60CLD using the JM60 GUI. However, it asks for a .s19 file to update the OSBDM. I have been attempting to find the correct .s19 file to do what the TWR-56F8257 originally did, but I cannot find the correct one. Does anyone know how I can find and update my MC9S08JM60CLD?

Please help!

Recommend you contact technical support for that.

Hi Daniel,

The OSBDM firmware is maintained by P&E Micro. The firmware is available from:

JM60-OSBDM Firmware Update Utility &raquo; P&amp;E Microcomputer Systems

This requires a HCS08 programmer. The required s19 files are part of the installation, I'm unsure if the DSC version is included. If not I suggest you contact P&E.

bye

pgo,

Thank you so much! You were absolutely correct! I downloaded the 'Firmware Updates & Recovery' program from P&amp;E Microcomputer Systems.
After running the installation, I connected to my device and selected the generic 'DSC' file.
It worked wonderfully! I now have the processor getting power again.

The best part: I didn't need the HCS08 programmer. By using the direct USB link and having the correct drivers, the tower board provided the necessary link to reprogram the MC9S08JM60CLD.

Thanks again!
