Other Parts Discussed in Thread: OMAP-L138

I use TDS560 and I can connect to DSP, but I can't connect to arm.

I want to write something to nand flash, so I modify some code on my arm project and connect to DSP.

I open that project and load is OK.

I've got a naked 138 board, and I compile and write "armubl & u-boot" to it by use TI "nand-flash-writer"

But I cannot see anything on UART when rebooting.

Do only "armubl & u-boot" is enough for me ? And why doesn't it boot?

To connect to the ARM, set the boot pins to emulation mode. Then reset the board and you should have no issue connecting to the ARM. You will have to run a DSP wakeup function from a GEL file in order to connect to the DSP.

Are you using the OMAP-L138 EVM or a custom board?

HI,

I'm using a custom board now. And I just want to wake up to U-Boot now.

Do you think I can do it just with u-boot file and arm-ubl file and write them to nand-flash (by connect to dsp)?

You should be able to. Make sure your arm-ubl file is an AIS file, created with either the command line or gui tool.
