Hello,
TOT U-Boot (commit 8fd4166c, compiled with ELDK 4.2) for the MPC8555CDS target is broken with the following symptoms:
[flash the 8fd4166c image and reset the board]
U-Boot 2008.10-rc2-00018-g8fd4166 (Sep 23 2008 - 10:23:59)
CPU: 8555E, Version: 1.1, (0x80790011) Core: E500, Version: 2.0, (0x80200020) Clock Configuration: CPU: 825 MHz, CCB: 330 MHz, DDR: 165 MHz (330 MT/s data rate), LBC: 82 MHz CPM: 330 Mhz L1: D-cache 32 kB enabled I-cache 32 kB enabled Board: CDS Version 0x11, PCI Slot 1 CPU Board Revision 0.0 (0x0000) PCI1: 32 bit, 33 MHz, sync PCI2: 32 bit, 66 MHz, sync I2C: ready DRAM: Initializing SDRAM: 64 MB DDR: 256 MB
And the output stops here, console is dead. Can't give more details as to what's going on the board -- don't have a HW debugger available.
After a power-cycle, the board doesn't go as far as the first time after reset:
U-Boot 2008.10-rc2-00018-g8fd4166 (Sep 23 2008 - 10:23:59)
CPU: 8555E, Version: 1.1, (0x80790011) Core: E500, Version: 2.0, (0x80200020) Clock Configuration: CPU: 825 MHz, CCB: 330 MHz, DDR: 165 MHz (330 MT/s data rate), LBC: 82 MHz CPM: 330 Mhz L1: D-cache 32 kB enabled I-cache 32 kB enabled
Subsequent power-cycles result in the same output, i.e., the output dies after the "I-cache 32 kB enabled" line.
The U-Boot works fine as of commit 71074abb, but can't do a full bisection at the moment (can't flash the board easily).
Brief search of the ML archives didn't reveal any such issue reported, so I'm posting this as a data point, and in the hopes that someone can take further investigation from here. I'll be happy to provide more details if needed, and might also be able to test a potential fix.
