Hi,
Im trying to port barebox to my Armadeus apf27 board (based on the Freescale
imx27 with a 512MiB NAND and 1GB of SDRAM).
I've first tried the phytec imx27 configuration and I got it worked until
the Linux uncompressing task (the machine ID is bad so I didn't expect it
will boot fine :)).
So I just copied the phycard-imx27 board directory and I followed the
boards.dox in order to add support for my board.
But when I've tried to boot again it was not working anymore ...
There are somethings stranges with the FEC, here is the result of a memory
display with both phytec and my own board :

The fec is working fine on the phytec but the same o my board make it crash:

Why I did'nt get the boad working with the same configuration ?

This means your phy is not configured correctly. Do you usse the correct
address (can be passed in platform_data).

GPIO pins which hold the phy in reset are another thing which might go
wrong.

Yes I've set the correct adress and it's why I don't have fffff like on the
phytec.
But in fact I had to change the fec_get_hwadrr() to make it work with my
board :
static int fec_get_hwaddr(struct eth_device *dev, unsigned char *mac)
{
int i;
int uninitialized = 0;
> for (i=0;i<6;i++) {
mac[6-1-i] = readl(&IIM_BANK_REG(0,(IIM0_MAC+i)));
}
> /* uninitialized if all 00 */
if ((mac[0] == 0) && (mac[1] == 0) && (mac[2] == 0) &&
(mac[3] == 0) && (mac[4] == 0) && (mac[5] == 0))
uninitialized = 1;
> /* uninitialized if all FF (could be safe) */
if ((mac[0] == 0xff) && (mac[1] == 0xff) && (mac[2] == 0xff) &&
(mac[3] == 0xff) && (mac[4] == 0xff) && (mac[5] == 0xff))
uninitialized = 1;
> return uninitialized;
}
Before this change it wasn't the case, I had no mac adress in barebox
start...
I also added a specific reset :
void fec_reset()
{
int i=0;
/* FEC RESET */
imx_gpio_mode(CFG_ETHPHY_RST | GPIO_OUT | GPIO_PUEN | GPIO_GPIO);
printf("Before PHY reset\n");
GPIO_CLEAR(CFG_ETHPHY_RST);
udelay(200);
GPIO_SET(CFG_ETHPHY_RST);
printf("After PHY reset\n");
}
And then I call it in the fec_probe() to ensure the fec is reset properly
before settings.
I already tested the fec on u-boot and it works fine, so i tought it can
help me with barebox but it seems there are some differences between codes.
For now Im trying to see if it can be a cpu frequence problem because I have
an errata on the pll that shifts all my frequencies and so I have to adjust
them in the lowlevelinit...
So I would like to know if the clock initialization is taking effect if I
boot from RAM ? Do I have t boot from flash ?
Thanks again.

Please generate proper diffs. I can't really read this.

fec_get_hwaddr error value in which case the core will generate a random
mac address. Looking at the code the driver seems to do this wihtout
changes.

the pll setup code is in your board, so it's in your hands.
Some PLL settings are safer to run from Flash or internal RAM instead of
SDRAM.
