Topic: need help for blinking led with imx233
i make my own board with imx233 qfn.
i am a newbie with imx uc and i try, for my first code to blink led.
i get source code from lyre project (use flaconwing) and i have problem :
when i start board without sd card or without configured sd, there is a timeout for 20 sec and uc go sleep.
when i start board with bootable sd card with bootlet code, uc start and wait infinitely.
sd card can't boot without bootlet code.
my question is where must i put code for blinking led ???
ps : i make bootable sd card with dd commande, i does'nt have jtag debugger.
i get 1, 1.2, 1.8 and 3.3V on vddX lines. (memory is 1.8V model).
