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 ..
