hi, why can not read device signature (lpc 2364)

Started by myn0601 November 22, 2007
hi, good afternoon, everybody,

I am using LPC2364, SSD1926 and the Touch screen LCD together to show
something on the LCD,

but now the LPC2364 and SSD1926 all do not have short circuit any
more, the 3 power supplier levels 5v , 3.3v , 1.8 v all there stable.

the MCU is connected to PC through UART0, max232 also powered
correctly, this part of circuitry refer to the MCB2300 evaluation
Board,

why I can not get the device signature from FlashMagi? any body can
tell me possible reason? thanks!

An Engineer's Guide to the LPC2100 Series

Hi,

Have you connected proper oscillator?
How are you reading the signature from flash magic?
I hope you can refer to flash programming section in the LPC2364 datasheet.

Since you are using Flash magic, I suggest you to use Tools-> Terminal
and try giving some commands and see, whats the response.

regards,
OST
