Qualcomm Reference Design Platform (RDP)

Qualcomm RDPs are development boards based on the Qualcomm IPQ series of SoCs. These SoCs are used as the application processors in WiFi router platforms. RDPs come in multiple variants with differences in storage medium (NOR, NAND, MMC), no. of USB and PCIe ports, n/w ports etc.

Installation

First, setup CROSS_COMPILE for aarch64. Then, build U-Boot for IPQ9574:

$ export CROSS_COMPILE=<aarch64 toolchain prefix>
$ make qcom_ipq9574_mmc_defconfig
$ make -j8

This will build u-boot.elf in the configured output directory.

The firmware expects the ELF images to be in MBN format. The elftombn.py tool can be used to convert the ELF images to MBN format.

IPQ9574: (MBN version 6)

$ python elftombn.py -f u-boot.elf -o u-boot.mbn -v6

IPQ5424: (MBN version 7)

$ python elftombn.py -f u-boot.elf -o u-boot.mbn -v7

Then install the resulting u-boot.mbn to the 0:APPSBL partition on your device with:

IPQ9574# tftpboot path/to/u-boot.mbn
IPQ9574# mmc part (note down the start & end block no.s of '0:APPSBL' partition)
IPQ9574# mmc erase <start blk no> <count>
IPQ9574# mmc write $fileaddr <blk no> <count>

U-Boot should be running after a reboot (reset).
