Hi there,

board/at91rm9200dk/memsetup.S and board/cmc_pu2/memsetup.S define

#define PIOC_ASR 0xFFFFF870
#define PIOC_BSR 0xFFFFF804
#define PIOC_PDR 0xFFFFF804

but according to the User Manunal is should have been:

#define PIOC_ASR 0xFFFFF870
#define PIOC_BSR 0xFFFFF874
#define PIOC_PDR 0xFFFFF804

Is that a bug or a feature?

[U-Boot-Users] Linux hangs on SCC2 (consol)

Hi ,

i use ELDKv3 kernel v2.4.24 , and i used make menuconfig ,and for MPC8260 I chosed SCC for console .

I have only one SCC1 port (it has only two pins Rx,Tx) but i cannot configure kernel to search for only one console , it hangs after asking for the second one:

Uncompressing Kernel Image ... OK
Memory BAT mapping: BAT2=64Mb, BAT3=0Mb, residual: 0Mb Linux version 2.4.24-pre2 (root at Setareh2) (gcc version .
.
.
Initializing RT netlink socket
Starting kswapd
CPM UART driver version 0.01
ttyS0 on SCC1 at 0x8000, BRG7
ttyS1 on SCC2

and hangs here , can anyone please tell me what is my problem? here is my menuconfig MPC8260 CPM configuration:

[*] Enable SCC console
[ ] CPM SCC Ethernet
[*] CPM FCC Ethernet
[*] Ethernet on FCC1
[*] Ethernet on FCC2
[*] Ethernet on FCC3
[ ] Use MDIO for PHY configuration

[ ] Support LXT970    PHY

PS: I must opologize for asking a linux question, (if i must ask it in other places , please tell me where can i ask),i asked it here , because my problem may be caused by uboot and exprienced by it's users.hope it is not irrelevant to uboot, and not to bother anyone.

Your posting is off topic here. This has nothing to do with U-Boot.

It's a typo. A fixed typo, to be precise :-)

Thanks for pointing out.
