#Script for ZY1000#Atmel ties SRST & TRST together, at which point it makes#no sense to use TRST, but use TMS instead.##The annoying thing with tying SRST & TRST together is that#there is no way to halt the CPU *before and during* the#SRST reset, which means that the CPU will run a number#of cycles before it can be halted(as much as milliseconds).reset_config srst_only srst_pulls_trstif { [info exists CHIPNAME] } {	   set  _CHIPNAME $CHIPNAME    } else {	    set  _CHIPNAME zy1000}if { [info exists ENDIAN] } {	   set  _ENDIAN $ENDIAN    } else {	    set  _ENDIAN little} #jtag scan chainif { [info exists CPUTAPID ] } {   set _CPUTAPID $CPUTAPID} else {   set _CPUTAPID 0x1f0f0f0f}jtag newtap $_CHIPNAME cpu -irlen 4 -ircapture 0x1 -irmask 0xf -expected-id $_CPUTAPIDset _TARGETNAME [format "%s.cpu" $_CHIPNAME]target create $_TARGETNAME arm7tdmi -endian $_ENDIAN -chain-position $_TARGETNAME -variant arm7tdmi-s_r4# at CPU CLK <32kHz this must be disabledarm7_9 fast_memory_access enablearm7_9 dcc_downloads enableflash bank ecosflash 0x01000000 0x200000 2 2 0 ecos/at91eb40a.elf$_TARGETNAME configure -event reset-init { 	# Set up chip selects & timings	mww 0xFFE00000 0x0100273D	mww 0xFFE00004 0x08002125	mww 0xFFEe0008 0x02002125	mww 0xFFE0000c 0x03002125	mww 0xFFE00010 0x40000000	mww 0xFFE00014 0x50000000	mww 0xFFE00018 0x60000000	mww 0xFFE0001c 0x70000000	mww 0xFFE00020 0x00000001	mww 0xFFE00024 0x00000000		# remap  	mww 0xFFFFF124 0xFFFFFFFF  	mww 0xffff0010 0x100	mww 0xffff0034 0x100		#disable 16x5x UART interrupts	mww 0x08020004 0}# required for usable performance.
