[U-Boot-Users] Issues with u-boot on PPC440EP Bamboo
by Josh Boyer 09 Aug '07

09 Aug '07

Hi All, I seem to have a Bamboo board that U-Boot hates. Using any version newer than 1.1.4, I get the following error on boot up: U-Boot 1.2.0-gb23b5475-dirty (Aug 9 2007 - 09:49:20) CPU: AMCC PowerPC 440EP Rev. B at 400 MHz (PLB=100, OPB=50, EBC=25 MHz) I2C boot EEPROM disabled Bootstrap Option D - Boot ROM Location EBC (16 bits) Internal PCI arbiter disabled, PCI async ext clock used 32 kB I-Cache 32 kB D-Cache Board: Bamboo - AMCC PPC440EP Evaluation Board I2C: ready DRAM: ERROR: DIMM 0, unsupported refresh rate/type. Replace the DIMM module with a supported DIMM. ERROR: Tcyc incorrect for DIMM in slot 0 ### ERROR ### Please RESET the board ### This is a stock board from AMCC from a couple years ago. I haven't done anything with the DIMMs in it, so they are whatever came with the board. Both PIBS and U-Boot 1.1.4 report a DRAM size of 192 MB, so I'm assuming something with the SDRAM probing in newer versions of U-Boot is causing the error above. Any ideas? josh

[U-Boot-Users] TEMAC support of Uboot on ML403
by Ming Liu 09 Aug '07

09 Aug '07

Dear all, Does anyone know that whether U-boot can support Xilinx TEMAC core to tftp the Linux kernel or not. In my design I am using TEMAC instead of the normal enet. While I found that in the Xilinx u-boot tree, there is only a directory for xilinx_enet instead of xilinx_temac. I am not sure if I am right, but I remember a long time before, there was a patch for supporting Xilinx TEMAC in U-boot. Any suggestion will be appreciated a lot for this topic. Thank you in advance for your telling. BR Ming _________________________________________________________________ 享用世界上最大的电子邮件系统― MSN Hotmail。 http://www.hotmail.com
