Hello!
Hi/Ahoj :)
I'm using latest git source of U-Boot on Raspberry Pi Compute Module and performance of fatload is quite bad. Does anyone have any clue about what can be wrong? Is it the lack of cache?
Sample boot log:
...
reading zImage 4003816 bytes read in 48930 ms (79.1 KiB/s)
I see this too. I bisected it to: 33fe2fb8df01 ARM: mmc: bcm283x: Remove get_timer_us() from mmc driver
Marek, this is the second symptom I bisected to this patch. Something seems quite wrong with it. Did changing to the other timer function change the timer tick rate or something? FWIW, "sleep 10" at the shell prompt appears to run for the correct amount of time, so I guess it's not that.
Hmmmm, get_timer() returns msecs, not usecs. I wonder what I was smoking. Can you try with the attached diff please (I only compile-tested it) ?
I think you meant Marek Vašut. I'm Marek by last name :).
We're both Czech though ;-)
Best regards, Marek Vasut
