# Flashing and Running an Image on the 8155P

## Qualcomm Snapdragon 8155P Board

This is a top view of the Qualcomm Snapdragon 8155P board.

## Set up the wiring

Several cables between the PC and the board are needed for flashing and debugging applications on the board:

- Power connector
- Micro USB is the FT serial console output
- Normal USB is the QFIL/Fastboot port (USB-A - USB A/USB C cable)
- DisplayPort cable is for Graphical output
- Ethernet port, for loading an application dynamically.

This is a wiring configuration example: power is ON, male USB-A is connected for flashing images, DisplayPort cable is connected for Graphical output.

Micro USB is connected for using the FT serial console.

## Switch to Fastboot Mode

To flash images on Qualcomm Snapdragon 8155P board install Fastboot Tool on Host OS. See, Fastboot Tool

Before flashing switch the board to the Fastboot Mode:

- Open serial connection with the board:

       putty /dev/ttyUSB0 -serial -sercfg 115200,8,1

- There are 2 options:

  - On the device, hold the volume key and power cycle the device.

  - Or press down arrow on the UART shell and power cycle the device.

- If the board switches to Fastboot Mode successfully, it prints following console output:

  Another way to check the board is in Fastboot Mode is to run the command:

       fastboot devices

## Flash images

The build script produces set of images for board partitions.

     boot.img, perf_dyn.img, misc_dyn.img, abl.elf, etc

After switching to Fastboot Mode images can be flashed to the board.

- When setting up for the first time, follow the images flashing procedure from GHS ES7_FinalCopy/ES7_customer_package_readme.docx:

       cd /work/ghs/sa8155/es7/es7_dev_env/hlos_dev_boot/apps/ghs_apps_proc/qc_bsp/out/chk/bin/target
       fastboot flash abl  abl.elf
       fastboot flash boot vmm-adp-gvm-sa8155/boot.img
       fastboot flash perf_dyn_a vmm-adp-gvm-sa8155/perf_dyn.img
       fastboot flash misc_dyn_a  vmm-adp-gvm-sa8155/misc_dyn.img

       cd /work/ghs/sa8155/es7/es7_dev_env/ES7_FinalCopy/Images/sa8155_hyp
       fastboot flash hyp_a hyp.mbn
       fastboot flash tz tz.mbn
       fastboot flash apdp apdp.mbn

       cd /work/ghs/sa8155/es7/es7_dev_env/hlos_dev_boot/apps/ghs_apps_proc/qc_bsp/out/chk/bin/target/fs
       fastboot flash gh_sys sys.img
       fastboot flash gh_persist ghs_persist.img
       fastboot flash gh_test ghs_test.img.sparse

       cd /work/ghs/sa8155/es7/es7_dev_env/hlos_dev_boot/apps/ghs_apps_proc/qc_bsp/prebuilt_NHLOS/adsp/asic_8150
       fastboot flash adsp adsp.img

       cd /work/ghs/sa8155/es7/es7_dev_env/hlos_dev_boot/lagvm/LINUX/android/out/target/product/msmnile_gvmgh
       fastboot flash vendor vendor.img

  Note: ES7_FinalCopy/ES7_customer_package_readme.docx is a part of QC [ES7] Customer package. Contact Qualcomm Support for more information.

- If this is not the first time flashing, then the monolith part should be flashed:

       cd /work/ghs/sa8155/es7/es7_dev_env/hlos_dev_boot/apps/ghs_apps_proc/qc_bsp/out/chk/bin/target
       fastboot flash boot vmm-adp-gvm-sa8155/boot.img

- Restart the board.

## Run Qt application on the board

- Open serial console:

       putty /dev/ttyUSB0 -serial -sercfg 115200,8,1

- Execute the command:

       rt <application name> Initial

- Run Qt application example:

  Qt application is running on Qualcomm Snapdragon 8155P Board and displayed on the connected screen.
