[U-Boot] loading S-record files

We can load binary files by loading them in RAM (offset 0x3000000) first and then copying them to Flash with the cp.b command.

Now we are trying to load our executable (in S-record format) in Flash with the loads command (load S-record) using U-boot.

It is my understanding that S-record files specify the exact location of all data, so I assume that loads will write the content directly to Flash (without the need to load it in RAM first). Is this correct ?

I tried loading an S-record file of which the data is mapped to RAM and that seems to work,
But when the S-record file contains records that map a chunk to Flash, it gives the following error:

Unknown command 'S325F8045B0042414E434F4E464947555245445F5354CD' - try 'help'
=> S325F8045B20415445524154494F4E414C5F5354417E


FYI: 0xf8000000 is the start of our Flash.
Our U-boot is based on 2008.10 version.
