Dear all:
We are Microelectronic Design and Applications (DMA) research group from University Carlos III of Madrid (Spain). At the moment, we are developing our own computational hardware platform, based on AMCC Sequoia board.
In the past, we used U-Boot 1.3.3 with AMCC Sequoia board, and PPC booted fine from NAND Flash. At the moment, with the same configuration of bootstrap (533MHz, NAND Boot, 33Mhz PCI) we are trying to use the last version of U-Boot (2010.06) on AMCC Sequoia board. But PPC doesnt boot well, because there arent any information on HyperTerminal.
We use ELDK 4.2 for compiling U-Boot 2010.06 nand image on the same way that we did it for U-Boot 1.3.3: $ export CROSS_COMPILE=ppc_4xxFP- $ PATH=$PATH:/opt/eldk/usr/bin:/opt/eldk/bin $ cd u-boot $ make distclean $ make sequoia_nand_config $ make all
We boot PPC from NOR FLASH with previous version of U-Boot, and then we program NAND Flash memory with U-Boot 2010.06 nand image. We also use the same commands to do it that we used with U-Boot 1.3.3: => loadb 100000 /* transfer the U-Boot image */ => nand erase ENTER => nand write 100000 0 70000 ENTER
After that, we put J2 jumper and select SW2 (OFF-OFF-OFF-OFF).
Are we missing something?
Thanks and Regards,
