Hi TsiChung,

I just downloaded it, and after a couple of silly hiccups, I got it to 
compile.  However, it did get very far.  I at first thought it was the 
call to icache_enable() at the end of cpu_init_f(), as gdb always got 
there, until I temporarily removed it discovered the real culprit.  It 
was the setup of CS2 for the NAND Flash.  I am 99% sure I have a 
M5329BFE Fire Engine, as I have the M5329EVB, but it seems something's 
wrong there.  If I pretent I have the M5329AFE (i.e. no NAND Flash), it 
works great!  Burned it to NOR and power-cycle - boots right up!

I would like to get the NAND working, though... Any ideas?

Thanks!
-Bob

My port currently works with the m5329evb, and supports the uart, flash, and sdram.  The timer is used for delays, but I'm not sure how thorough it is implemented.  I don't have rtc, the clock PLL is quirky, and I especially miss the fec.  I read up on the Ethernet last Friday, but I hadn't gotten a chance to attempt that.  Given my project resources, think I'll use yours instead!  I'll certainly look at what you've got, and am very interested in future developments!
