This code comes from the i.MX28 ROM and means:
Requested data beyond the end of a section.
Maybe your entry point is wrong? I just had a look at our .bd file and
it looks like this:
sources {
power_prep="./power_prep/power_prep";
u_boot="/home/sha/dude/bosch/OSELAS.BSP-Bosch-SCM/platform-scm/build-target/barebox-2012.05.0/barebox";
}
section (0) {
//----------------------------------------------------------
// Power Supply initialization
//----------------------------------------------------------
load power_prep;
load ivt (entry = power_prep:_start) > 0x8000;
hab call 0x8000;
//----------------------------------------------------------
// Load and call u_boot - ELF ARM image
//----------------------------------------------------------
load u_boot;
load ivt (entry = u_boot:exception_vectors) > 0x8000;
hab call 0x8000;
}
