TMDX28069USB

After working with the USB Control stick for some weeks without problem now suddenly the control stick behaves strange. When connecting with CCSV4 to the target the view of all registers appears for two seconds or so but after that only Core registers and CLA1 are displayed. In the disassembly window the CLA  program memory at 0x9000 is displayed, in the weeks before Flash memory had been displayed. When loading a program there comes the error message " data verification error at 0x3f4209". Looks that like a flash problem?

Thanks in advance

    Klaus,

    It seems like you are in the CLA debug session, that is why you are seeing the CLA1 and core registers only. Also all CLA code is stored in ram3 @ 0x9000 which is why youre disassembly starts at that point.If you arent debugging/using any CLA code you probably dont want to connect the second debug session to the target.

    You can identify the CLA debug session with its title  "Texas Insrtuments XDS100v1 USB Emulator_0/CLA_0" or something similar to that.

    As far as the data verification error at 0x3f4209 goes, you're right it looks like a flash issue. The controlSTICK cd had the following exe, ti_c2000_f2806x_flash_setup_4.2.0.1.exe in the extras folder of the CCS install. You need to install this for flash support. There are some other requirements concerning version compatibility and such thats covered in the quickstart guide
