Maybe a stupid question, but does anyone no why there is no call to flush_cache() at the end of do_fat_fsload()?
A bug perhaps?
I haven't tried it on the latest u-boot, but I had an issue the other day where I was trying to load a VxWorks image from a Compact Flash card on a MPC8572-based board. The same image booted fine with tftpboot, but when I loaded the image off of the CF card using the fatload command, the image didn't boot. I confirmed that image was copied faithfully into DRAM. I then noticed that the tftpload command (netboot_common) has a call to flush_cache() after the download to memory completes, so I added the following to the end of do_fat_fsload():
...
/* flush cache */ flush_cache(offset, size);
return 0; }
Then the image booted...
Makes perfect sense. Best would be if you could send a proper patch to fix this.
Thanks.
Best regards, Stefan
