To boot the Linux kernel, we use the U-Boot tftp command to download the kernel uImage to SDRAM. The kernel Oops occurred
during the booting process in most case. But the dump messages are different all the times. Sometimes the booting process can
reached the Linux user login step. Except that, the same ulmage can boot properly on the EVM board.
The U_Boot version is 1.3.3 offered by TI.
The Linux kernel is MontaVista 2.6.18 offered by TI.
USB module was not selected when built the kernel ulmage in “make menuconfig” method.
In addition, there are some difference between the EVM board and the customer's board.
The SDRAM CLK pin is connecting to a pull up resistance in the EVM board, but the customer's board can only work when
connecting to a 3.3K pull down resistance.
The SDRAM part Number is IS42S16160 what is same as the EVM board, but the package and version is different.
Blow is the part of the schematic of the OMAP-L137 board. The SDRAM CLK pin is connecting to a 3.3K pull down resistance.
Do you have any suggestion about this issue? Thank you very much!
