Can someone please tell me if the ARM7TMDI's JTAG port is proper and 'standards compliant' as far a JTAG goes or do you actually need to use the ARM MultiICE or compatible? I don't initially want to do ICE or ICD with it, I can initially use Angel for that, i just want to load code into the boot flash (an external chip AT49BV4096A that would be connected as the boot flash to the EBI of an AT91R40008)? I want to get into ARM development, but on the cheap, with GNU tools, and a homemade board. i think i have the basics of the hardware design knucled down, and have got the gnu tools going, but am unsure how to flash boot code into the chip. It woudl also be alright if there was some way to load a program inot the internal ram of the '40008 cos there is 256kbyte of it and you can execute code from it.
ps as you may have gathered i dont really know what im talking about, but i dont claim to either. has anyone made a homemade cheap-as dev board before. Seems feasible - AT91 with onchip ram ~US$20, flash ~$10, power supplies (3.3 and 1.8V) ~$6, oscilator, reset supervisor etc ~$5, PCB maybe ~$20, it come to about ~~50 bucks US? and the AT91 eval board is about 200 bucks??
any thoughts, cheers hugo
