How to program flash of custom OMAP board?

How to program flash of custom OMAP board?

[Li Weichen]

Hi everyone,

I have a custom OMAP 5912 board with Intel 28F256J3C NOR Flash.  But I don't
know how to download the u-boot to it.  With OSK, the factory
u-boot-1.1.1.out can be loaded in CCS and download itself while running.
But due to the different flash type, this factory u-boot cannot be
programmed to the custom OMAP board.

Does anyone have any idea to resolve this problem?

Thank you in advance and best regards!

For many OMAP-u-boot ports, if you have a JTAG debugger, you can connect
to the board, initialize clocks & ddr via script, load u-boot into
memory and execute it.  Now you can download using either your JTAG or
ether the image you want to burn and use u-boot to burn that image.

Richard W.

But after I load the u-boot and run, it seems not work, only stop at the
beginning of the codes and there is not any information at the UART.

Perhaps it needs a tweak. In the OMAP u-boots I've worked on, I made
sure to add a couple checks to see if the address it was executing from
was SDRAM or its compiled address.  If that is the case it should skip
the clock and DDR init phases as you can't be running in DDR if it
wasn't inited (ie via gel).

It might be these were removed when the OSK port was done.  They
shouldn't be to hard to put back.  If they are missing you will crash
when the memory goes away underneath the code executing.

When you build the u-boot, be sure it is pointing the UART port you are
using.

Hi,

 If you find no message on the UART, is the u-boot running
on the DDR or Flash?

 If you mean the latter, the number of device errata may
impact your design.

	(see page 30)

 If I remember correctly, the u-boot must be re-configured to  
include the 28F256J3 driver (while the single MTD driver supports
28F128J3 & 28F256J3 in Linux).

 BTW, this product already supports the OMAP5912 + 
28F256J3C, and all the behind-sence things will be done 
automatically by pressing the single button.

 The board below (OMAP5912 + 28F256J3) is programmed
the bootloader with this tool.

 Good luck.

  Ishigami
