From mboxrd@z Thu Jan 1 00:00:00 1970 From: Xianghua Xiao Date: 13 Apr 2003 11:24:21 -0500 Subject: [U-Boot-Users] Debug from SDRAM In-Reply-To: References: Message-ID: <1050251062.1080.10.camel@spurs> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de I have a new board(the chip is just being made) with flash on its local bus, but the localbus-flash is not working. i modified the code on a few key configs including CFG_RAMBOOT, CFG_ENV_IS_NOWHERE and CFG_NO_FLASH(grep them in u-boot and find their use) to run U-Boot in DDR directly. Of course you need use your debugger to initilize DDR/SDRAM before you download U-Boot to it. if you have a working flash, you really don't need to do so and it's better to boot from flash and wait for U-Boot to configure your SDRAM instead... regards, xianghua On Wed, 2003-04-09 at 09:09, Roel Loeffen wrote: > Hello, > > I've donwloaded the ELF file with the PowerTAP pro, everything works fine. > The ELF File directs the PowerTAP download to 0xFFFx.xxxx (Flash Memory) > > Is there a possibility to Compile and Link the code in a way the code can > run from SDRAM? > > Thx Roel > > > > > ------------------------------------------------------- > This SF.net email is sponsored by: Etnus, makers of TotalView, The debugger > for complex code.
