    JTAG Wiggler connections ?

    ocdemon internal error 43 to eltonjohn I know that Wiggler was supported in FastChip 2.2.0. From the command line, start "spiderd -c ARM_Jtag_Wiggler" to use the Wiggler cable with the A7. This uses MaCraigor's ARM drivers. I don't know if this way can be used with E5 chips. vladz

    Using jstag program for arm7 developing

    iar arm7 jtag lpt As keen wrote you need compiler( for example greenhills) and wigller interface. Schematic of Wiggler is available from https://jtag-arm9.sourceforge.net/hardware.html it is all. Only greenhills supports the Wiggler. With ADS you must use expensive ICE. Best regards Vlad
