hi, I am new to u-boot and have few doubts. I am trying to run uboot on custom board. I am using jtag(XDS 510 USB) to debug board. I have am3517 processor from ti. I have MT29C4G48MAZAPAKQ-5 IT chip which contains nand flash and lpddr. While making hardware I have not connected chip select 0 to this chip so I am not able to boot code from nand. So I am loading x-loader on internal sram at 0x40208800 and its running and I am getting message "x-loader hangs" on terminal Then I am loading uboot on ddr at 0x80e80000. When I run the code in step mode the code is running upto start_armboot() function (u-boot/lib_arm/board.c) and goes into a for loop where it cheks for init_sequence. While code reaches upto this point some times it jumps to unkown location like 0x0000000C and then stops working and the same thing happens when it is in init_sequence when i reach to that point I am not understanding why is it happenig?? Is there any relation of CS0 to be connected to nand in order to run u-boot because I have seen lot places CS0 being used in code. I am using am3517_craneboard files.

thank you
