[PATCH] pico-imx7d: Add initial support

Vanessa Maegima
Add the initial support for pico-imx7d board based on Wig Cheng's
source code.

Add support for eMMC, USB gadget, I2C, PMIC and Ethernet.

+How to update U-Boot on pico-imx7d board
+----------------------------------------
+
+Required software on the host PC:
+
+- imx_usb_loader: https://github.com/boundarydevices/imx_usb_loader
+
+Build U-Boot for pico:
+
+$ make mrproper
+$ make pico-imx7d_defconfig
+$ make
+
+This generates the U-Boot binary called u-boot.imx.
+
+Put pico board in USB download mode (refer to the PICO-iMX7D Quick Start Guide
+page 3)
+
+Connect a USB to serial adapter between the host PC and pico.
+
+Connect a USB cable between the OTG pico port and the host PC.
+
+Open a terminal program such as minicom.
+
+Copy u-boot.imx to the imx_usb_loader folder.
+
+Load u-boot.imx via USB:
+
+$ sudo ./imx_usb u-boot.imx
+
+Then U-Boot starts and its messages appear in the console program.
+
+Use the default environment variables:
+
+=> env default -f -a
+=> saveenv
+
+Run the UMS command:
+=> ums 0 mmc 0
+
+Transfer u-boot.imx to be flashed into the eMMC:
+
+$ sudo dd if=u-boot.imx of=/dev/sdX bs=1K seek=1; sync
+
+Remove power from the pico board.
+
+Put pico board into normal boot mode.
+
+Power up the board and the new updated U-Boot should boot from eMMC.

Re: [PATCH] pico-imx7d: Add initial support

Jagan Teki
In reply to this post by Vanessa Maegima
Though the code look good and similar approach of existing boards, I'm
little concern of continue the same legacy and w/o trying new feature
like fdt.

We've few i.MX boards which uses fdt support please refer the same.
I'm commenting below what all the code can removed ans use it with
dts.

Re: [PATCH] pico-imx7d: Add initial support

It is worth a couple og thoughts. Even if the path to a u-boot
configured via fdt is clear, this should be done if this does not block
other feature that are maybe important for the project - and this is
known only by the board maintainer. I do not talk about this particular
board - the issue is general and I remain general.

For example, it looks to me that having a single binary for multiple
variants of the board cannot be easy reached. There is a DTS for each
variant and this means a binary for each of them. This is ok for some
projects, it is not ok for some other ones. And I cannot constrain
people to go into a direction when they lose features.

I did quite the same approach with SPL / u-boot.imx. I understand that
some projects want to stick with a single binary instead of two, it
remains a decision of board maintainer. No block on my site.

Last concern is related to size in SPL. imx6.Solo has just 64Kb RAM, but
less are available because a part is reserved to the BootRom (or HAB, or
whatever). And putting a lot of stuff inside SPL is not possible, then.

After saying all this, back to the specific case. Vanessa, you are not
using SPL and you have put the RAM configuration into the DCD table.
Then it is everything fix and you cannot have more variants. That means
your board has not the drawbacks I mentioned above. It could be a good
candidate to use dts. What do you think ?

Best regards,
Stefano Babic

>> +
>> +Build U-Boot for pico:
>> +

>> +Load u-boot.imx via USB:
>> +
>> +$ sudo ./imx_usb u-boot.imx
>> +
>> +Then U-Boot starts and its messages appear in the console program.
>> +
>> +Use the default environment variables:
>> +
>> +=> env default -f -a

>> +
>> +Run the UMS command:

>> +
>> +Transfer u-boot.imx to be flashed into the eMMC:
>> +
>> +$ sudo dd if=u-boot.imx of=/dev/sdX bs=1K seek=1; sync
>> +
>> +Remove power from the pico board.
>> +
>> +Put pico board into normal boot mode.
>> +
>> +Power up the board and the new updated U-Boot should boot from eMMC.

Re: [PATCH] pico-imx7d: Add initial support

Vanessa Maegima
Hi Stefano, Jagan,

I have been trying to add the dts support for this board but I could not make Ethernet, I2C and PMIC support work using dts.

I am still trying to add this support but I don't know how much time it can take. I'm new to U-Boot.

Can you please consider applying the original patch?

Thanks in advance!

Regards,
Vanessa Maegima

It is worth a couple og thoughts. Even if the path to a u-boot
configured via fdt is clear, this should be done if this does not block
other feature that are maybe important for the project - and this is
known only by the board maintainer. I do not talk about this particular
board - the issue is general and I remain general.

For example, it looks to me that having a single binary for multiple
variants of the board cannot be easy reached. There is a DTS for each
variant and this means a binary for each of them. This is ok for some
projects, it is not ok for some other ones. And I cannot constrain
people to go into a direction when they lose features.

I did quite the same approach with SPL / u-boot.imx. I understand that
some projects want to stick with a single binary instead of two, it
remains a decision of board maintainer. No block on my site.

Last concern is related to size in SPL. imx6.Solo has just 64Kb RAM, but
less are available because a part is reserved to the BootRom (or HAB, or
whatever). And putting a lot of stuff inside SPL is not possible, then.

After saying all this, back to the specific case. Vanessa, you are not
using SPL and you have put the RAM configuration into the DCD table.
Then it is everything fix and you cannot have more variants. That means
your board has not the drawbacks I mentioned above. It could be a good
candidate to use dts. What do you think ?

Best regards,
Stefano Babic

I will add the dts support and send a v2.
