Hello, I know this topic has been discussed in great details, but I have been unable to port Redboot for my custom board properly for a few weeks, and I can't find whats the problem. I wonder if anyone would be kind enough or have the time to help me see what could be the problem. The specifications of my board is as follow: Samsung SC4510B01 MPU 2 x AMD AM29F002BB 256KB Flash 2 x Samsung K4S281632F-TC75 (8Mx16)16MB SDRAM I previously tried to port using the ARME7T template and modify according to the ARM7TDBoard settings but that did not work. Then I tried using the Samsung SNDS template as it also has flash and SDRAM. However it also did not work. There was no errors in compiling and building of the RedBoot image. But when I try to run through hyperterminal after loading it into the flash, it only showed a random single character on the screen. I am thinking could it be the problem with the SDRAM? This is because when I tried to write "AAAA" or "5555" into the SDRAM memory using the AxD I'll get some inconsistent data written to some random memory locations. When I write "FFFF" or "0000" it works fine. Could this result in the problem when reboot is remapped onto the SDRAM from ROM? I attached my mlt files and hal_platform_setup.h. Hopefully that'll help in pointing out which part of the porting I did wrong. I know its really tedious and I would greatly appreciate your help! Thanks! __________________________________ Do you Yahoo!? Dress up your holiday email, Hollywood style. Learn more. http://celebrity.mail.yahoo.com
