Unable to program MC9S12E256 due to "Secured Device" Error

Discussion created by Pedro Duquesne on May 11, 2012

Im trying to download some code to my MC9S12E256 with CW (I have the USBDMLT drivers installed), but CW gives me a message saying the device might be secured and then It's unable to program the device. I also tried using the HCS12FlashProgrammer.exe that came with the drivers I downloaded, but then I get some error about being unable to program the device because the TCL script returned an error. The drop down list of devices that appears in the Flash Programmer doesnt include the E256 version of my device, so every time I use the "Detect Device"button, it gives me the "Default_" option.

Any suggestionds? Thanks in advance.
