[OpenOCD-user] openocd, openjtag, and at91sam7s-ek

[David R. <re...@os...>]

G'day,

I'm running linux and have openocd-0.7.0, an openjtag device (from
100ASK), and an at91sam7s-ek eval kit with an at91sam7s256.  My
initial test project is Atmel's getting-started-project. 

My problem is that I'm unable to flash the chip.

openocd is recognizing the openjtag and the chip, as indicated by:

    Info : device: 4 "2232C"
    Info : deviceID: 0x1457:0x5118
    Info : SerialNumber: ...
    Info : Description: USB<=>JTAG&RS232 A
    Info : clock speed 6000 kHz
    Info : JTAG tap: at91sam7s256.cpu tap/device found: 0x3f0f0f0f \
        (mfg: 0x787, part: 0xf0f0, ver: 0x3) 
    Info : Embedded ICE version 1 
    Info : at91sam7s256.cpu: hardware has 2 breakpoint/watchpoint units 
    Info : JTAG tap: at91sam7s256.cpu tap/device found: \
       0x3f0f0f0f (mfg: 0x787, part: 0xf0f0, ver: 0x3)

However, openocd isn't happy with the programming:

    ** Programming Started **
    auto erase enabled
    Warn : no flash bank found for address 8000
    Warn : no flash bank found for address 11f04
    wrote 0 bytes from file getting-started-project.elf in 0.108909s \
        (0.000 KiB/s) 
    ** Programming Finished **
    ** Verify Started **
    Error: checksum mismatch - attempting binary compare
    ...

Addresses 8000 and 11f04 appear in the load map as:

    LOAD /usr/arm-unknown-linux-gnueabi/usr/lib/crtn.o
      0x0000000000008000   PROVIDE (__executable_start, 0x8000)
      0x0000000000008174   0x8000 + SIZEOF_HEADERS)

    .exception_ranges
     *(.exception_ranges .exception_ranges*)
      0x0000000000009da8  . = (ALIGN (0x8000) - ((0x8000 - .) &0x7fff))
      0x0000000000011f04  . = DATA_SEGMENT_ALIGN (0x8000, 0x1000)

Can anybody point me towards a solution to the "no flash bank" problem?

Thank you.

David
