This bitbake class supports following use cases. > **Note:** Refer https://github.com/Xilinx/dfx-mgr/blob/master/README.md for > shell.json and accel.json file content. * **Zynq-7000 and ZynqMP**: * Design: Vivado flat design. * Input files to firmware recipes: .bit, .dtsi or dtbo and shell.json (optional) * Usage Examples: ``` SRC_URI = " \ file://.bit \ file://.dtsi \ file://shell.json \ " ``` ``` SRC_URI = " \ file://.bit \ file://.dtbo \ file://shell.json \ " ``` * **ZynqMP and Versal**: * Design: Vivado DFx design. * Input files to firmware recipes: .bit(ZynqMP) or .pdi(Versal), .dtsi or dtbo shell.json or accel.json (optional) and .xclbin (optional). * Usage Examples: ``` # ZynqMP DFx Static SRC_URI = " \ file://.bit \ file://.dtsi \ file://shell.json \ file://.xclbin \ " ``` ``` # ZynqMP DFx Static SRC_URI = " \ file://.bit \ file://.dtbo \ file://shell.json \ file://.xclbin \ " ``` ``` # ZynqMP DFx RP SRC_URI = " \ file://.bit \ file://.dtsi \ file://accel.json \ file://.xclbin \ " ``` ``` # ZynqMP DFx RP SRC_URI = " \ file://.bit \ file://.dtbo \ file://accel.json \ file://.xclbin \ " ``` ``` # Versal DFx Static SRC_URI = " \ file://.pdi \ file://.dtsi \ file://shell.json \ file://.xclbin \ " ``` ``` # Versal DFx Static SRC_URI = " \ file://.pdi \ file://.dtbo \ file://shell.json \ file://.xclbin \ " ``` ``` # Versal DFx RP SRC_URI = " \ file://.pdi \ file://.dtsi \ file://accel.json \ file://.xclbin \ " ``` ``` # Versal DFx RP SRC_URI = " \ file://.pdi \ file://.dtbo \ file://accel.json \ file://.xclbin \ " ``` --- ## How to create a firmware recipe app 1. Follow [Building Instructions](../README.building.md) upto step 4. 2. Create recipes-firmware directory in meta layer and copy the .bit/pdi, .dtsi/dtbo, .json and .xclbin file to these directories. ``` $ mkdir -p /recipes-fimrware//files $ cp -r /*.{bit or pdi, dtsi or dtbo, shell.json or accel.json and .xclbin} /recipes-fimrware//files ``` 3. Now create the recipes for flat or static or partial firmware using recipetool. ``` $ recipetool create -o /recipes-fimrware//firmware-app-name.bb file:////recipes-fimrware//files ``` 4. Modify the recipe and inherit fpgamanager_custom bbclass as shown below. ``` SUMMARY = "Full Bitstream loading zcu111-pl-demo firmware using fpgamanager_custom bbclass" LICENSE = "MIT" LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302" inherit fpgamanager_custom SRC_URI = "\ file://zcu111-pl-demo.bit \ file://zcu111-pl-demo.dtsi \ " COMPATIBLE_MACHINE ?= "^$" COMPATIBLE_MACHINE:zynqmp = "zynqmp" ``` 5. Add firmware-recipe app to image and enable fpga-overlay machine features to local.conf as shown below. > **Note:** fpga-manager-script provides fpgautil tool to load .bit/pdi and dtbo > at runtime linux. ``` MACHINE_FEATURES += "fpga-overlay" IMAGE_INSTALL:append = " \ firmware-app-name \ fpga-manager-script \ " ``` 6. Follow [Building Instructions](../README.building.md) and continue from step 5. 7. Once images are built firmware app files will be installed on target_rootfs. ``` # /lib/firmware/xilinx/firmware-app-name ``` --- ## Test Procedure on Target * Once Linux boots on target, use fpgautil command to load .bit or .pdi and corresponding dt overlay as shown below. > **Note:** firmware can be loaded only with sudo or root permissions. --- ### Loading PL bitstream or pdi and dt overlay * ZynqMP ``` yocto-zynqmp-generic-20231:~$ sudo su yocto-zynqmp-generic-20231:/home/petalinux# cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 11: 13309 13021 13673 14170 GICv2 30 Level arch_timer 14: 0 0 0 0 GICv2 67 Level zynqmp_ipi 15: 0 0 0 0 GICv2 175 Level arm-pmu 16: 0 0 0 0 GICv2 176 Level arm-pmu 17: 0 0 0 0 GICv2 177 Level arm-pmu 18: 0 0 0 0 GICv2 178 Level arm-pmu 19: 0 0 0 0 GICv2 58 Level ffa60000.rtc 20: 0 0 0 0 GICv2 59 Level ffa60000.rtc 21: 0 0 0 0 GICv2 42 Level ff960000.memory-controller 22: 0 0 0 0 GICv2 88 Level ams-irq 23: 0 0 0 0 GICv2 155 Level axi-pmon, axi-pmon 24: 327 0 0 0 GICv2 53 Level xuartps 27: 0 0 0 0 GICv2 156 Level zynqmp-dma 28: 0 0 0 0 GICv2 157 Level zynqmp-dma 29: 0 0 0 0 GICv2 158 Level zynqmp-dma 30: 0 0 0 0 GICv2 159 Level zynqmp-dma 31: 0 0 0 0 GICv2 160 Level zynqmp-dma 32: 0 0 0 0 GICv2 161 Level zynqmp-dma 33: 0 0 0 0 GICv2 162 Level zynqmp-dma 34: 0 0 0 0 GICv2 163 Level zynqmp-dma 35: 0 0 0 0 GICv2 109 Level zynqmp-dma 36: 0 0 0 0 GICv2 110 Level zynqmp-dma 37: 0 0 0 0 GICv2 111 Level zynqmp-dma 38: 0 0 0 0 GICv2 112 Level zynqmp-dma 39: 0 0 0 0 GICv2 113 Level zynqmp-dma 40: 0 0 0 0 GICv2 114 Level zynqmp-dma 41: 0 0 0 0 GICv2 115 Level zynqmp-dma 42: 0 0 0 0 GICv2 116 Level zynqmp-dma 43: 0 0 0 0 GICv2 154 Level fd4c0000.dma-controller 44: 5938 0 0 0 GICv2 47 Level ff0f0000.spi 45: 76 0 0 0 GICv2 95 Level eth0, eth0 46: 0 0 0 0 GICv2 57 Level axi-pmon, axi-pmon 47: 4802 0 0 0 GICv2 49 Level cdns-i2c 48: 501 0 0 0 GICv2 50 Level cdns-i2c 50: 0 0 0 0 GICv2 84 Edge ff150000.watchdog 51: 0 0 0 0 GICv2 151 Level fd4a0000.display 52: 548 0 0 0 GICv2 81 Level mmc0 53: 0 0 0 0 GICv2 165 Level ahci-ceva[fd0c0000.ahci] 54: 0 0 0 0 GICv2 97 Level xhci-hcd:usb1 55: 0 0 0 0 zynq-gpio 22 Edge sw19 IPI0: 64 25 87 38 Rescheduling interrupts IPI1: 1933 6579 1096 5686 Function call interrupts IPI2: 0 0 0 0 CPU stop interrupts IPI3: 0 0 0 0 CPU stop (for crash dump) interrupts IPI4: 0 0 0 0 Timer broadcast interrupts IPI5: 0 0 0 0 IRQ work interrupts IPI6: 0 0 0 0 CPU wake-up interrupts Err: 0 yocto-zynqmp-generic-20231:/home/petalinux# tree /lib/firmware/ /lib/firmware/ `-- xilinx `-- zcu111-pl-demo |-- zcu111-pl-demo.bit.bin `-- zcu111-pl-demo.dtbo 2 directories, 2 files yocto-zynqmp-generic-20231:/home/petalinux# fpgautil -b /lib/firmware/xilinx/zcu111-pl-demo/zcu111-pl-demo.bit -o /lib/firmware/xilinx/zcu111-pl-demo/zcu111-pl-demo.dtbo [ 91.039773] fpga_manager fpga0: writing zcu111-pl-demo.bit to Xilinx ZynqMP FPGA Manager [ 91.528214] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /fpga-full/firmware-name [ 91.538354] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /fpga-full/pid [ 91.547598] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /fpga-full/resets [ 91.557087] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /fpga-full/uid [ 91.566804] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /__symbols__/afi0 [ 91.576312] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /__symbols__/clocking0 [ 91.586255] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /__symbols__/axi_gpio_0 [ 91.596280] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /__symbols__/misc_clk_0 [ 91.606300] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /__symbols__/axi_gpio_1 [ 91.616325] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /__symbols__/axi_gpio_2 [ 91.626342] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /__symbols__/axi_uartlite_0 [ 91.636705] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /__symbols__/ddr4_0 [ 91.661849] gpio gpiochip3: (a0000000.gpio): not an immutable chip, please consider fixing it!
