Hello all, I want to program my device (LPC2106) via the JTAG interface with a homebrew software. The problem is that i can't find any documentation on philips JTAG programming. I understood that many dev-kits manufacturers don't know how to program the flash with the JTAG. They execute and debug the code in RAM but when you want to make your card work in standalone mode you must use the...

How to? On LPC2106 et al, use P0.22..31 while JTAG enabled As best as I can determine, there's no way to use the most signficant bits in the GPIO (P0) if the primary JTAG is enabled enven though the secondary JTAG is not in use. Yes? ------------------------------------

Hi, I build the simple board with LPC2103 to start learning LPC21xx. I have success to access the serial bootloader and software download with it. Next step I build the RDI-JTAG (Wiggler type), and use H-JTAG dll with Keil Software. The Wiggler-JTAG seems to work OK, since I have success to Flash it with H-FLASHER, the H-JTAG also recognized my LPC2103. The problem come when I try the...

I am having a problem when trying to disable the JTAG interface on an LPC213X. I have a pulldown resistor attached to P0.31. On my JTAG interface, I apply 3.3V to P0.31 and everything works fine. What I have noticed, is that when my JTAG interface is not connected (p0.31 pulled low) I no longer recieve EINT0 interrupt on P0.16. Can anyone tell me if they have seen this behaviour? Or...

Olimex says, in their LPC2106 board document "Important: when JTAG is enabled P0.18-P1.31 ports take their JTAG alternative function no matter of PINSEL register value, so during debugging with JTAG these ports are not available for the user program." I found these words after fumbling for hours thinking I was at fault. The NXP user manual says that if the ARM's pin 26, RTCK, is high at powe...
