Hi Andy, thanks for your statement.
The IENIT0 Pin of the LPC2378 (that is used to set the device into ISP mode) is driven by RTS and IRESET is driven by DTR signals done with 2 transistors; I found this in the MCB2300 eval board drawings and made the same in my design. The bootloader version of LPC2378 is V3.2.
This morning when I powered up the whole stuff, I could read the device ID but minutes later the chip didn't respond again. Sometime it was possible to communicate and program the device, but I didn't find out what's wrong.
hi friend
he friend i m rahul from india
i want to use LPC2378 for one of my projects.
i m new to ARM.
i want to make an isp device for my LPC2378.
I want some circuit for that.
do u have any working circuit for that.
can u send me at my mail id: er_rahulkapoor@yahoo.co.in
.
also i want to ask one more thing. do we definitely need a bootloader for programming the arm. or it is only needed when we want to program it in c.I mean that is it possible to program arm in assembly language without bootloader
