XDS510 Connect to Targer -- Fatal Error

Other Parts Discussed in Thread: TMS470R1A256

 Hi there,

Hi I have a problem using the Spectrum Digital XDS510 USB emulator. When trying to connect to a target (ARM7) this is what i get:

Error connecting to the target: Error 0x80000244/-2131

Fatal Error during: Initialization, OCS,

Cannot access register at 0x00000000

P.S : I have run the SDconfig utility. It is able to connect and emulator driver is setup correctly.

Hope you can help :)

    Hi,

    A quick question: did this configuration ever work before? The reason is that you seem to be using a complex configuration and therefore anything can happen, from the basic target configuration file (.ccxml) to the internal parameters of the device (presence of ICEPICK, some internal emulation addresses, etc.).

    One additional detail: ARM7 devices may require Adaptive clocking to work (something the XDS510USB emulator does not support). In this case you can work around this by dividing the frequency until you get a successful connection.

    Also, depending on the device, you may need to short the TCK and RTCK signals as shown in section 3 of the page below:

    I am able to connect to my (ancient) TMS470R1A256, which is an ARM7-based device using the trick above.

    Regards,
