Not sure what the expectation is...

Actually no, I don't use U-Boot on the M4 (so far). For Linux on the Vybrid M4, I use a special boot loader which runs on the A5 Linux. On Vybrid (the variant we use at least) boots always from the A5 first, hence I have a running Linux. Or alternatively, I could run the M4 from U-Boot running on the A5. So far, I had no need to run U-Boot on the M4. The reason I was interested in Thumb2 was the size: Due to lack of 5V on the Colibri module we need to load the boot loader using Vybrid's serial loader over UART which is somewhat slow. So the 25% reduction of size means 25% less download time... -- Stefan _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
