Hi,
To write u-boot to the flash memory, what kind of flash programmer do you guys usually use?
An Abatron BDI2000 JTAG based debugger. : P
Arguably the best choice, and the one I use as well.
The flash I am using is Fujitsu MBM29DL640E.
IIRC, I've used the BDI2000 to program same part before. ; )
I asked around and the average price is around $900. That is too expensive for me.
Oh, well, I guess the BDI200 may cost more but you'll get more mileage too.
Do anyone know any programmer under $500?
Erm, you can use a parallel to JTAG dongle and host JTAG software to bit-bang the JTAG of your processor to program flash. Google around or wait for other to give more details.
One that I saw recently was http://warmcat.com/milksop/cheaptag.html but you will have to dig around for software. And sometimes, you can get free stuff from vendor seminars like the upcoming http://www.atmel.com/seminar/mcu/default_dgk.asp . It just depends on if it will work with your project, and if you can make it to the seminar.
