Hello everyone.
I have been trying to perform this task for several days:
Target:
I want to set the SerDes protocol with the value 4555h according to the table shown in the document QorIQ LS1043A Reference Manual, Rev. 6, 07/2020 (Pag. 1916)
Problem:
To generate the boot I am using flex-builder, in particular flexbuild_lsdk1712. I saw from the documentation Layerscape Software Development Kit 17.12 Documentation, Rev. 0, 02/201 that it is possible to make the file firmware_ls1043ardb_uboot_sdboot.img with the following command: flex-builder -i mkfw -m ls1043ardb -b sd -B uboot.
I do this because I need to generate the boot from SD with U-Boot 2017 on it.
I have replace the old RCW with the new one in the file ls1043ardb_rcw_sd.cfg.
So inside the ls1043ardb_rcw_sd.cfg file there must be this:
#PBL preamble and RCW header
aa55aa55 01ee0100
# RCW
06100010 0a000000 00000000 00000000
45550002 80404012 60040000 c1002000
00000000 00000000 00000000 00038800
00000000 00001100 00000096 00000001
unfortunately with this modification the boot from the sd does not start me.
Question:
The RCW is correct for performing SerDes protocol with the value 4555h ?
