Hi,
yeah, I have some insane amount of cleanup patches and fixes already. I will post them once I'm done. What I am sorely missing is the UniPHY register interface documentation, it looks like that is not public, so I don't exactly know if what sequencer.c does is really correct. Sometimes I have serious doubts about that too . Can you give me the documentation please ?
Have you seen this link[1]?
Yes, but that is by far not all of the registers used in the sequencer.c, is it ?
Looks like it's in the entire emi.pdf file[1]. Please look at volume 3, or page 531 of 895. The section for the UniPHY.
I extracted all the possible addresses used in the sequencer while cleaning it up, they're below. I cannot find these in any documentation. I checked the EMI RM, sure, but there seems to be many more registers all around the place than what are described in the EMI RM. Any ideas please ? Maybe this is not even the UniPHY anymore ?
Hi!
I'll try to get those questions answered for you shortly.
Thanks!
BTW, I tested out our your branch, but I think I'm missing a step as where to put the SPL DTB?
U-Boot SPL 2015.07-rc3-00100-ga2e2da6 (Jul 21 2015 - 17:15:54) drivers/ddr/altera/sequencer.c: Preparing to start memory calibration drivers/ddr/altera/sequencer.c: CALIBRATION PASSED drivers/ddr/altera/sequencer.c: Calibration complete Missing DTB ### ERROR ### Please RESET the board ###
Do:
make u-boot-with-spl-dtb.sfp
This will produce u-boot-with-spl-dtb.sfp, which you write directly to that 0xa2 socfpga boot partition. It includes U-Boot SPL, DTB and U-Boot. You will also need to define CONFIG_SPL_MMC_SUPPORT in include/configs/socfpga_common.h as I didn't solve how to configure this on per-board basis, do this before building the U-Boot of course.
