[U-Boot-Users] U-boot for MCF5329

[Liew Tsi Chung-r5aahp]

Robert,

	The NAND feature has not implemented in u-boot yet. There are some conflicts. First, CFG_CS2_BASE 0x00800000 should change to 0x0080. Second, even the above was fixed, u-boot was unable to bring up w/wo icache_enable(). Still, trying to trace the issue.

Regards,
TsiChung

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!
