[PPCBoot-users] how to drive a new board

Hi Sir,
 I want to drive a ppc860 board which is not included in the /board subdirectory , and i make a new dir in
/board/scop860 ,so which files I need to add in ? My board contains a SST-39vf040(512k bytes flash as
bootrom,PLCC), two HYUNDAI-hy57v281620hct-6(SDRAM) ,and a INTEL-te28f320 , and
24lc32(eeprom),lxt905lc(ethernet),ds1305(rtc). how can i drive these things ? i think the first step
is to bulid a ppcboot.bin to the bootrom . who can tell me what should i do ? 

Thank you very much !!

yours sincerely 
                                         michael xie

[PPCBoot-users] U-Boot or PPC Boot

Roel Loeffen <RL <at> prodrive.nl>
2003-04-01 09:30:23 GMT

Hello,

I want to start using a Boot Loader for:
- PMC Module with a Motorola 7410 and a Marvell Galileo Discorery bridge.
- CodeWarrior and Power-Tap Pro, (debugging)

I've found some infomation about PPCBoot, and it seams to be an intresting
Boot Loader for me.
But in the users-list I've read that the development discontinued??

Is U-Boot a predecessor of PPCBoot?
Which one should I use?

Thank you, Roel

No, U-Boot is the successor of PPCboot. Thus, you should start with U-boot, 
as it is the newer one.

Good luck,
Andreas

PPCBoot is a dead project. Development has been discontinued half a year ago. Please use the U-Boot project instead.

And read the README, which contains a  (short)  section  about  steps
needed  to port U-Boot to new hardware. If you need more information,
read the source code. Or hire an expert.

[PPCBoot-users] how to use fec

PASCAL Joseph <joseph.pascal <at> c-s.fr>
2003-04-08 09:42:56 GMT

hi!
i'm student and  i work on mpc862 which use ppcboot for launch 
application and test some memories

i'have a fec driver for a phy(ltx973)
this driver have function :
eth_init(), eth_send()..

here is my function eth_send():
int eth_send(volatile void *packet, int length)
{
	int j, rc;
	volatile immap_t *immr = (immap_t *) CFG_IMMR;
	volatile fec_t *fecp = &(immr->im_cpm.cp_fec);

	/* section 16.9.23.3
	 * Wait for ready
	 */
	j = 0;
	while ((rtx->txbd[txIdx].cbd_sc & BD_ENET_TX_READY) && (j<TOUT_LOOP)) {
		udelay(1);
		j++;
	}
	if (j>=TOUT_LOOP) {
		printf("TX not ready\n");
	}

	rtx->txbd[txIdx].cbd_bufaddr = (uint)packet;
	rtx->txbd[txIdx].cbd_datlen  = length;
	rtx->txbd[txIdx].cbd_sc |= BD_ENET_TX_READY | BD_ENET_TX_LAST;

I hope you are aware of the fact that the PPCBoot prokject  has  been
discontinued,  so it makes little sense to put any development effort
in a dead project. Use the  U-Boot  project  instead,  which  is  the
successor.

I don't understand why you would rename functions? The code you  copy
is obviously the fec_send() function from cpu/mpc8xx/fec.c

Please explain why you mess with this code - it should work fine as is.

> my question is what would be the format of my packet??

It's a standard ethernet packet.

i know that ppcboot is dead project but i work on a part of this project 
that had been began 2 years ago. And it is the person who had work on 
fec.c who had rename the function and i don't know why...

another questions

  a)is there necessary to put in the packet the protocole (iP,arp etc..)?

b)  my packet format is it correct:( destination address, source 
address, length and data)?

c) the begening of my packet address must be the begining of my transmit 
buffer address, right?

I think it is dangerous to work on code  you  don't  understand.  The
original  PPCboot  vode  was  probably  working  find.  If  you don;t
understand the modifications, and why they are necessary,  you  might
be just wasting your time.

> another questions

Depends on what you want  to  do.  If  you  want  to  implement  some
protocol, then yes.

Again, I don;t understand what you are trying to do. All these things
are working fine. This is definitely not  the  place  to  touch  when
porting PPCBoot to a new board.

> b)  my packet format is it correct:( destination address, source

Ummm... please read the relevant RFC's and related documentation. 

This discussion goes far beyond the scope of this mailing list.
