This is not truth!
Can you please provide further details to back your claim ?
Yes, see a patch with explanation which I meanwhile sent: https://patchwork.ozlabs.org/project/uboot/patch/20230404202805.8523-1-pali@...
This very much adds a comment that looks like the content of the second paragraph of my reply, see below.
It is a good thing you mention the aforementioned patch, since exactly one line past the changes you implemented is the following piece of code:
https://source.denx.de/u-boot/u-boot/-/blob/master/common/spl/spl_mmc.c#L382
" int default_spl_mmc_emmc_boot_partition(struct mmc *mmc) ... part = (mmc->part_config >> 3) & PART_ACCESS_MASK; if (part == 7) part = 0; "
Which maps 7 to 0 .
This kind of screaming feedback with zero additional information is worthless, sorry. Before you proceed with any further replies, please have a look at JEDEC JESD84-B51 section 7.4.69 PARTITION_CONFIG Bit[5:3] BOOT_PARTITION_ENABLE , this is what is being discussed here. Value 1/2 is either BOOT HW partition, value 0/7 is treated as USER HW partition by the boot code.
Please read the paragraph above, I do not see any reply to it and I think that might put the conversation back on track.
I have read it and the reply with explanation is already there in my first email and also in the linked email.
What you have written above in not truth.
Very well, I think I will defer further judgement to the MMC maintainer and stop participating in this thread. Constructive feedback is welcome.
I see that this is your standard trolling reaction for a very long time if you do not have any relevant argument; or when you are lazy to read replies from other people.
