Changing ethernet port speed

[Hamid Amirrad]

Hi,

I see that the u-boot has been recently upgraded to 2019.04.
I created the image as follows:
1. Checked out the code
2. . setup evb-ast2500
3. time bitbake obmc-phosphor-image

Then I copied the created image (bmc-image)
from /trunk/build/evb-ast2500/tmp/deploy/images/evb-ast2500/obmc-phosphor-image-evb-ast2500-20221122160306.static.mtd.all.tar
to my LC having BMC module. I used ./socflash.sh to upgrade the BMC image
to one just created. After upgrade is done, I still see the old u-boot
version (below). Is this something else I need to do for the u-boot to be
at revision 2019?

ast# version

U-Boot 2016.07 (Jun 10 2020 - 10:12:49 +0000)
arm-openbmc-linux-gnueabi-gcc (GCC) 11.2.0
GNU ld (GNU Binutils) 2.37.20210721

I am using BMC simulator on another server and on that the u-boot revision
is fine (below). Not sure why u-boot is not at 2019 when I compile the code
directly.
ast# version
U-Boot 2019.04 (Nov 10 2022 - 00:12:58 +0000)

arm-openbmc-linux-gnueabi-gcc (GCC) 12.2.0
GNU ld (GNU Binutils) 2.39.0.20220819

Any help would be greatly appreciated.

Thanks,
Hamid
