Because I study u-boot just now, I do not know how to study it and solve the problems that when I migrate it to LPC2294 board, please you help me, thank you very much! I have some questions 1. #define FLASH_SST200A 0x0040 /* SST 39xF200A ID ( 2M = 128K x 16 ) */ #define FLASH_SST400A 0x0042 /* SST 39xF400A ID ( 4M = 256K x 16 ) */ #define FLASH_SST800A 0x0044 /* SST 39xF800A ID ( 8M = 512K x 16 ) */ #define FLASH_SST160A 0x0046 /* SST 39xF160A ID ( 16M = 1M x 16 ) */ #define FLASH_SST320 0x0048 /* SST 39xF160A ID ( 16M = 1M x 16 ) */ #define FLASH_SST640 0x004A /* SST 39xF160A ID ( 16M = 1M x 16 ) */ #define FLASH_SST040 0x000E /* SST 39xF040 ID (512KB = 4Mbit x 8 ) */ what these define comes? is in the produce datasheet? I couldn't find in the datasheet ,I just find the device id and Manfacturer's ID. and I use the nor flash sst339vf1601. 2. which file's are define the CPU frequency set ? 3. how can I debug the u-boot? I can't display any information of through the serial port ? 4. is the any doc about the source cold struct of the u-boot? Thank you very much!!! Yours sincerely, Yong xu
