| Post subject: | Carambola2 Bringup - Uboot unresponsive |
Hi, I've wired up a carambola2 to a new board and am a little stuck. I've got some output from the console (below), but at the end of that the device stops and is unresponsive to serial commands (checking on a scope, I see the tx/rx pins going), so the system appears to be just stopped. Anybody have an idea why it's not booting or I can't get a response from uboot? Thanks in advance, dean U-Boot 1.1.4 (Feb 8 2013 - 11:41:32) AP121-2MB (ar9330) U-boot DRAM: sri ar7240_ddr_initial_config(145): python ddr init #### TAP VALUE 1 = f, 2 = 10 64 MB Top of RAM usable for U-Boot at: 84000000 Reserving 212k for U-Boot at: 83fc8000 Reserving 192k for malloc() at: 83f98000 Reserving 44 Bytes for Board Info at: 83f97fd4 Reserving 36 Bytes for Global Data at: 83f97fb0 Reserving 128k for boot params() at: 83f77fb0 Stack Pointer at: 83f77f98 Now running in RAM - U-Boot at: 83fc8000 Flash Manuf Id 0xef, DeviceId0 0x40, DeviceId1 0x18 flash size 16777216, sector count = 256 Flash: 16 MB In: serial Out: serial Err: serial Net: ag7240_enet_initialize...

Anybody got a working Carambola2 with a console attached? If some kind soul can post a log of a working uboot boot sequence that might help in my troubleshooting. |

[quote="adamheinrich"]Here is the U-Boot log you asked for. I did not notice your request earlier, sorry. Thanks, Adam! So, I'm stumped as to why the module gets stuck there. Anybody else have any suggestions? I'll keep trying to get in touch directly with somebody at 8devices. |

How do you have your Carambola connected? Is it the dev board or just the module? How do you power it? |

Do you have it powered properly? Can't some current peak stop the module? |
