NXP i.MX8MN EVK Evaluation Board
================================
Board comes with either:
* 2GiB of LPDDR4 RAM
* 2GiB of DDR4 RAM
barebox supports both variants with the same image.
Downloading DDR PHY Firmware
----------------------------
As a part of DDR intialization routine NXP i.MX8MN EVK requires and
uses several binary firmware blobs that are distributed under a
separate EULA and cannot be included in Barebox. In order to obtain
them do the following::
wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.12.bin
chmod +x firmware-imx-8.12.bin
./firmware-imx-8.12.bin
Executing that file should produce a EULA acceptance dialog as well as
result in the following files:
- lpddr4_pmu_train_1d_dmem.bin
- lpddr4_pmu_train_1d_imem.bin
- lpddr4_pmu_train_2d_dmem.bin
- lpddr4_pmu_train_2d_imem.bin
- ddr4_dmem_1d_201810.bin
- ddr4_imem_1d_201810.bin
- ddr4_dmem_2d_201810.bin
- ddr4_imem_2d_201810.bin
As a last step of this process those files need to be placed in
"firmware/"::
for f in lpddr4_pmu_train_1d_dmem.bin \
lpddr4_pmu_train_1d_imem.bin \
lpddr4_pmu_train_2d_dmem.bin \
lpddr4_pmu_train_2d_imem.bin; \
do \
cp firmware-imx-8.0/firmware/ddr/synopsys/${f} \
firmware/${f}; \
done
for f in ddr4_dmem_1d_201810.bin \
ddr4_imem_1d_201810.bin \
ddr4_dmem_2d_201810.bin \
ddr4_imem_2d_201810.bin; \
do \
cp firmware-imx-8.0/firmware/ddr/synopsys/${f} \
firmware/${f%_201810.bin}.bin; \
done
Build barebox
=============
