From bda849d033feed3d185a6bf610206aecf8bc0e27 Mon Sep 17 00:00:00 2001 From: oharboe Date: Mon, 23 Mar 2009 19:12:42 +0000 Subject: [PATCH] Uwe Hermann eal _CPUTAPID entry for the LPC2148. I don't know if they're the same for all LPC214x, this number is from an Olimex LPC-H2148. The chip on that board is LPC2148FBD64. Also fix a few cosmetic issues and comments in the file and add more docs and pointers to the datasheet. git-svn-id: svn://svn.berlios.de/openocd/trunk@1427 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/target/target/lpc2148.cfg | 46 ++++++++++++++++++----------------- 1 file changed, 24 insertions(+), 22 deletions(-) diff --git a/src/target/target/lpc2148.cfg b/src/target/target/lpc2148.cfg index 7b701ab6..a728195c 100644 --- a/src/target/target/lpc2148.cfg +++ b/src/target/target/lpc2148.cfg @@ -1,49 +1,51 @@ - if { [info exists CHIPNAME] } { - set _CHIPNAME $CHIPNAME -} else { - set _CHIPNAME lpc2148 + set _CHIPNAME $CHIPNAME +} else { + set _CHIPNAME lpc2148 } -if { [info exists ENDIAN] } { - set _ENDIAN $ENDIAN -} else { - set _ENDIAN little +if { [info exists ENDIAN] } { + set _ENDIAN $ENDIAN +} else { + set _ENDIAN little } if { [info exists CPUTAPID ] } { set _CPUTAPID $CPUTAPID } else { - # force an error till we get a good number - set _CPUTAPID 0xffffffff + set _CPUTAPID 0x4f1f0f0f } -#delays on reset lines jtag_nsrst_delay 200 jtag_ntrst_delay 200 -# NOTE!!!
