From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Williams Date: Mon, 02 Feb 2004 13:35:07 -0800 Subject: [U-Boot-Users] Help w/ U-Boot vs/ ppc405GPr MAL Message-ID: <28662-94578@sneakemail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm porting U-Boot to a PPC405GPr board of our own design, and I'm having trouble getting the ethernet working. Specifically, when I try to do anything network related, it hangs in ppc_4xx_eth_init. I added some test prints and find that I'm getting an un-clearable error interrupt. I've added some test prints to dump the obvious registers, here's a snippet: XXXX Entering ppc_4xx_eth_init ENET Speed is 10 Mbps - HALF duplex connection XXXX about to enable interrupts... MAL error occured.... ISR = 0 UIC = 7f0000 MAL_DEF = 2e0000 MAL_ERR= 260000 XXXX Entering ppc_4xx_eth_init XXXX about to enable interrupts... XXXX Leaving ppc_4xx_eth_init MAL error occured.... ISR = 0 UIC = 7f0000 MAL_DEF = 2e0000 MAL_ERR= 260000 XXXX Entering ppc_4xx_eth_init XXXX about to enable interrupts... XXXX Leaving ppc_4xx_eth_init ... and so on. It is looping infinitely on the un-cleared error interrupt. I'm struggling w/ PHY/MII/MAL learning curves, as well as U-Boot learning, so clues welcome. - -- Steve Williams "The woods are lovely, dark and deep. steve at icarus.com But I have promises to keep, http://www.icarus.com and lines to code before I sleep, http://www.picturel.com And lines to code before I sleep." -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFAHsKLrPt1Sc2b3ikRAtXDAJ4qsMmJrxGx4RmZkHP6ia7YgUnYZwCfZmFo EoS+6IDcrpey6NqR3A+vVaA= =WXm/ -----END PGP SIGNATURE-----
