Thank you for reply me. My nas is synology ds416slim. here is the offical GPL source site: https://sourceforge.net/projects/dsgpl/files/Synology%20NAS%20GPL%20Source/8451branch/armada38x-source/ I think that synology doesn't update and miss some code at the site. here is my boot message: Quote BootROM - 1.73 Booting from SPI flash General initialization - Version: 1.0by linkt - uBoot
I replace original 512mb ram chip with 1gb ram chip, and read f1001410, f1001504... original ram register value. disassemble u-boot.bin, search for initializing code. I can't find any related code to modify. It's different from old armada xp chip. anyone could give me a hint to find and modify it? thanks a lot! sorry for my poor english.by linkt - uBoot
