hi to all,
first of all you need nice tool for arm7 developing.
- compiler: ads, sdt, greenhills, iar etc
- jtg interface to pc: wiggler(1$) other some k$.
Thats all, only greenhills suports wiggler & macraigor.
Approach: must do somehing by yourself:
- write sw which burn you appl. in flash
- semihosting approach (!=wiggler) or
- via jtag download sw in ram which will via rs232
download appl. sw & burn it in flash & that appr.
cost almoust nothing ..
wiggler=lpt+hc245+flat cable (lpt <==> jtag interface)
direct to the jtag pins of arm7.
Flow chart:
- run wigger & wigg. support sw & set arm7 mode to [0.0]
- via jtag download script file to config. arm7 memory®s
- compile support sw for those ram (supp. serial burning)
- run sw in ram, must get response on rs232
- send appl. sw to rs232(S3 motorola format) sw in ram will
burn incoming appl. sw in flash
- change arm7 mode to [1.0] & after reset sw from flash will
wakeup ..
regards Keen

As keen wrote you need compiler( for example greenhills) and wigller interface.
Schematic of Wiggler is available from
http://jtag-arm9.sourceforge.net/hardware.html
it is all.
Only greenhills supports the Wiggler. With ADS you must use expensive ICE.
Best regards
Vlad

Hello,
GreenHills 3.6 is here on my disc, but I have not full license file
for it anybody can supplay this ful license file ?
ragards Keen
p.s.
Vladz your GreenHill arm 2.0.1 tool with the fix works but
the utility for ICE debugger doesn't. Only arm micro browsing
is available, debuging on chip via wiggler does not work, tested.

hi, keen
I see 3 different PC stations with installed Multi2000 v2.0.1, that works with support of debuging via wiggler without problems. I tested it only under Wi98, I don't now if it works under win2000/XP.
Could you PM me abut your poblems with Multi2000 ?
