I've been following some of this list for a while now, particularly regarding FTDI based JTAG tool development. I only recently noticed that I no longer needed to patch into ft2232.c, but instead could simply write a configuration file for my FT4232H based dongle. Since I don't use the provided d2xx driver, I don't have too many speed issues. So I'm excited the code is getting cleaned up. However, I've got a bit of a problem. I have a unique JTAG dongle that allows me to select the target voltage. I typically use a python script for this (there was a libmpsse project somewhere, and I added a little additional SPI support and it has python bindings). However, it would be extraordinarily nice to be able to do this directly through OpenOCD. I noticed that there are several commands for adapters in general that get added during OpenOCD initialization, however, since this feature isn't present in EVERY FTDI JTAG adapter, I wanted to be able to add scriptable commands either throug h the interface script, or on top of the FTDI code, but without polluting the FTDI code. This is where the problem comes in: Basically I have to open one port as an SPI interface temporarily, send some commands then I'm set and can act like a simple FTDI JTAG. 1) I don't see any way to really do what I need through the scripting interface 2) I didn't want to add a MOSTLY IDENTICAL JTAG driver into the mix.
Is there any way to do this WITHOUT having to add another "mostly identical" JTAG driver? It is unbelievably convenient to just write a script and have support for my adapter. ------------------------------------------------------------------------------ Android is increasing in popularity, but the open development platform that developers love is also attractive to malware creators.
