[U-Boot-Users] Where is the head ?

[quantika at katamail.com]

I'm new to this project and I'm trying to locate the flow of the program, where it starts, where the main is, just to familiarize with the code. Can anyone give me some indication about where the flow starts ? The board I'm looking at is smdk2410, but any suggustion would be appreciate 
Thanks Bruno

[U-Boot-Users] Where is the head ?

[Jerry Van Baren]

Welcome to the right list ;-)

Read the readme, it has a lot of valuable information
<http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;h=6f610082224e54fc0a31246cdea7ad688df1e6d1;hb=83784bf63fa8dcf9c530226ab122463e95e9050f;f=README#l3141>

Read the linker control file, it is what determines the code that ends 
up in the reset vector
<http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;h=f4fbf969c3cf6445dd210053c319e591440dc3ae;hb=83784bf63fa8dcf9c530226ab122463e95e9050f;f=board/smdk2410/u-boot.lds#l35>

Hmm, cpu/arm920t/start.o:
<http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;h=4603cf573376fdfaa5b7b88933c6b1190591976a;hb=83784bf63fa8dcf9c530226ab122463e95e9050f;f=cpu/arm920t/start.S>

Porting guide section of the readme: :-)
<http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;h=6f610082224e54fc0a31246cdea7ad688df1e6d1;hb=83784bf63fa8dcf9c530226ab122463e95e9050f;f=README#l3347>

replace head with start and it's done ;-)

1. cpu/arm920t/start.S
2. board/smdk2410/lowlevel_init.S
3. board/smdk2410/smdk2410.c

ciao
