Hi all, We have already developed a flash programmer using a wiggler compatible JTAG interface, directly manipulating the JTAG pins (TCK, TDI, TDO, TMS) through the parallel port. We would like to speed up the process using a Raven compatible interface (actually we have a Chameleon POD). We haven't found any documentation about the interface of this device with a parallel port. Per...

Hi there! Does anybody has a software which I may use for programming my flash device (AT29c040a) through the MCU's JTAG port? The MCU is LH75411 from Sharp which has a ARM7-TDMI core. I have a wiggler and the macraigor's free OCD programmer in place. Both are working fine for programming the internal RAM of the MCU. For programming the flash device, the OCD programmer is obviously not...
