Hi all, i am trying to use SAM-ICE and SAMBA 2.6 to program my AT91SAM7S256 board. I can program via Olimex JTAG and OpenOCD but cannot debug (for some odd reason) via Olimex ( it loads forever, 27% done...). I can debug via SAM-ICE but not load flash! I get the error reason as written in the subject line when I hit the "Send file" button and after a looong while the Samba loader times out. Anyone have a solution??? Thanks in any case for looking into the problem! Regards Nils

I don't know much about the Segger J-Link/SAM-ICE but as far as I know the adaptive clocking can be disabled and fixed clocking can be used which should help. I also do not use SAM-BA and don't know if or where the clocking-mode can be configured in SAM-BA. If there is no option in SAM-BA try if you can used JLINK.EXE from the Segger Software-Package to change the setting.

In Samba NOTHING can be set, Changing in JLINK gave the same error, even down to 2 kHz clocking! I will now skip the Samba approach and run with ARM-JTAG-USB and Open-OCD instead. Although I have a little problem starting up the debug session. It continuous load 27% !!! Jim Lynch tip with Norwegian reset (power-off/power-on) does not help. Sigh... Best regards, Nils
