STR9 Booting from flash bank1

Richard G

Hi

I'm trying to get an application to run from flash bank 1 I have followed the instruction in the article
http://www.keil.com/support/docs/3347.htm
without success I have also tried the example code that goes with instructions still without success. Whenever I try to download the project I get a Flash timeout when attempting to write to 0x00000000.
I can run/debug applications from bank 0 so I know the J-tag connection is ok.
Is there anything I'm missing?

    It might be that your HW is causing these problems. Make sure that nTRST and nRESET are connected (ULINK <-> Target).

    Check also which chip HW revision you have. There are some problems described in the errata for earlier versions (rev B).

    Try also reducing the JTAG max. clock.
