'51, HC08/12, MSP430, TMS370, COP8 and similar  are longer on market and 
most of them (excluded TMS370) have Flash/ISP/IAP/ICSP memory. Which one is 
more popular than AVR/PIC? Look that many manufacturers changed politics and 
now we have lot of free (limited) C compilers, free programmers etc.

Sure, but if tools will be expensive, speed of rising will be small - in 
most "small" applications, not in industry. I don't see any reason for 
paying 100$ or more for simple program for Flash programming via JTAG. This 
is necessary for programming uCs like STR family, OKI ARM family and older 
Atmel AT91.

Complete JTAG spec (with IEEE1532 included) I have (can send if someone 
needs) and know very well. The "secret" is not here, unfortunately.

Hmmm, popularity of ARM is a problem of manufacturers not mine. I'd like to 
develop simple JTAG Flash programmer only.

Offense? ;-))
