Hello all,

I have just upgraded my hardware from Rev B to Rev C chips of AT91SAM7S128. But i am facing a strange problem when try to download and debug code through IAR Embedded Workbench for ARM with J-Link Jtag device from segger. Same project with same download settings programming the Rev B chips but not the REV C. However Rev C chips are being programmed correctly using J-Flash utility and then can be debug as well. But IAR is unable to program the Rev C chip some how and not writing to ROM/Flash any thing. I wonder if any one have experience such an issue before and now the exact reason to solve the problem. It will be really helpful if some one can share the appropriate information.

Regards... Dani:(

Perhaps you want to get an update from IAR which has the most recent flash applets for programming the chip. You don't mention a version, but a call to your IAR support rep should work.

Thanks cptTitanic,

I am using IAR 5.41 version.

hello dani,
i would suspect that the the startup-macro of EWARM isn't initializing the PLL the right way.
what macro file do you use (look at General options -> Debugger -> Use macro file)
does the debug log show any error messages?

regards
gerhard

Hi gerhard,

The mac file is at91sam7s-ek-flash.mac and here is the log for both Rev B and Rev C MCU respectively. Please see if you can guess anything.

For Rev B>>>>>>>>>>>>>>>>>>

Hi everybody, especially Danni:

I have exactly the same problem, With the same CPU but of 2008 year, I can download without problem, as a result, it works fine. Now we have just set up new cards with this new version (revision C) it does not work. However, I have proved if I download it in SRAM mode the Stack pointer goes to the correct address works and as a result, the CPU works. But when I switch off the CPU the memory is erased.

Did you solve this problem?Could you give some advice?

I look forward to reading from you,

Aritz

hello,
sounds like a problem of the flashloader.
try to use the j-link flashloader.
select options => debugger => download and uncheck "use flash loader".
now the j-link flashloader should be used.
eventually update j-link driver.

regards
gerhard
