Hi,
I'm trying to debug SAM9-L9260 board /AT91SAM9260 chip/ using the latest GIT
openocd checkout, FTDI-based dongle and libftdi-0.16. I made the following
minor fix to the board cfg:
-----------------------------------------------------------------------------
diff --git a/tcl/board/olimex_sam9_l9260.cfg b/tcl/board/olimex_sam9_l9260.cfg
index 935d7cd..5c4714e 100644
--- a/tcl/board/olimex_sam9_l9260.cfg
+++ b/tcl/board/olimex_sam9_l9260.cfg
@@ -26,7 +26,7 @@ $_TARGETNAME configure -event reset-start {
# RSTC_MR : enable user reset, reset length is 64 slow clock cycles. MM
# be enabled... use physical address.
- arm926ejs mww phys 0xfffffd08 0xa5000501
+ mww phys 0xfffffd08 0xa5000501
}
$_TARGETNAME configure -event reset-init {
-----------------------------------------------------------------------------
But OpenOCD reports address translation error when I issue "reset init", even
though MMU is reported as disabled. Am I doing something wrong? Should I
replace all "mww" invocations in the board cfg file with "mww phys"? A full
debug log follows.
Regards,
Dimitar
