Flashing AM1808 using OMAP-L138 Serial Flasher.

Other Parts Discussed in Thread: AM1808, OMAP-L138

I made a AM1808 custom board without DDR memory to reduce cost.

I am trying to flash using Serial Flasher (sfh_OMAP-L138.exe.)

But Serial Flasher stops with below message.

(AIS Parse): BOOTME received!

I know that UBL is loaded into the internal RAM memory and DDR isn't necessary.

However other board that has DDR complete flashing.

 

Does the sfh_OMAP-L138.exe program use the DDR memory?

What image (appication image or uart ubl) does it load into the internal RAM after receving BOOTME.

  • this flash program in sf.net is kinda "stupid" and slow.

    but I could make sure, DDR is in use by the flash program, the flash program transfer a small UBL and run the UBL then flash the SPI rom for you.

    because of this, I made a new programmer by VC6 and rewrite a small UBL to do that.

     

    if you just wanna program for a few times, just use BSL to program the SPI flash, slow but work, like 10 minutes at least to program the UBL and U-BOOT. check my post for the programmer for detail.

    good luck.
