What do you mean, you don't need xloader, u-boot SPL can replace it.
Yes and no. No, becaue you nor I have no Nokia's signing key(s) to sign SPL binary for OMAP's secure boot ROM. IIRC N950/N9 is even more strict regarding that, am I right?
You are right, we cannot sign SPL binary for N900 because we do not have key. Signing key has only somebody in Nokia (or in TI). I do not have N950/N9 so I do not know anything about new devices.
I know. So ... ? Basically you can use the TI flashes too since it all goes through the bootrom, right?
Butrom requires signed binary.
Yes and format of signed binary is not published by TI (there are only some RE info about Motorola Omap devices).
What I tried: I created mtd image where was X-Loader, NOLO and U-Boot. QEmu RX51 successfull booted this image and I got serial console and video screen output.
But when I created mtd image where was only X-Loader an U-Boot, QEmu RX51 was unable to boot (it freezed).
Why? Where? You know you can debug U-Boot in QEMU with GDB and diag the problem properly?
Any volunteers? (I own N900 too, ah, I own 3 of tham, damnit)
I can try to play with SPL U-Boot binary and X-Loader in qemu. But this and next month I do not have time for it...
