Xilinx csu. Or, a table table as per binary or Hex values basis. Single thread (AXI-ID) operation for both read and write channels CSU_DMA operates synchronously in the “csu_main_clk” or PMC clock domain Target CSU_DMA frequency of 400MHz max DST DMA will only issue a write AXI command if the corresponding write data is available in the write data FIFO – Store and Forward. On the left is the secure processor block that contains a triple redundant processor for controlling boot operation. Tamper monitoring and response. In u-boot and Linux, an IPI request is sent to the PMU, and the PMUFW will use the xilfpga library to copy the bitstream to the PCAP with CSU_DMA. (Note: you must enable a wake-up source first otherwise the kernel will Learn about building and customizing the First Stage Bootloader (FSBL) for Zynq UltraScale+ MPSoC, including features, options, and common FAQs. CSUDMA provides an efficient data transfer mechanism between the PSS's Memory and the CSU Stream Peripherals. There are three interrupts from CSU (PS) to PL as CSU WDT Interrupt, CSU DMA Interrupt, and CSU interrupt. In I'm seeing the folowing build errors when I try to rebuild pmu firmware (either from xsct, manually or yocto). The CSU authenticates the FSBL, and optionally the PMUFW, while in internal memory. •后配置阶段 (Post-configuration) 开始执行FSBL之后，CSU ROM代码进入后配置阶段，该阶段负责系统干预响应。 CSU硬件提供持续的硬件支持，以验证文件，通过PCAP配置PL，存储和管理安全密钥以及解密文件。 这个阶段会启动SSBL，就是Linux的bootloader，开始引导启动Linux CSU_BR_ERROR (PMU_GLOBAL) Register Description Register Name CSU_BR_ERROR Offset Address 0x0000000528 Absolute Address 0x00FFD80528 (PMU_GLOBAL) Width 32 Type mixedMixed types. PMU Firmware loading by CBR will be needed in the cases where the customer board has an onboard regulator that needs to be programmed to bring up the boot processor's power rail. Then checks the image for any encrypted partitions. To implement this feature, I had a look at the FSBL source code, since it performs reconfiguration during the boot Summarizes the software-centric information required for designing with AMD Zynq™ UltraScale+™ MPSoCs. Provides information on CSUDMA Standalone driver for Xilinx devices, including installation, configuration, and usage details. The CSU interrupt status register holds the interrupt bits PMU firmware can be loaded by either FSBL or CSU BootROM (CBR). 8 Scan清除功能 归零化过程中，所有的存储元素都要移位归零，然后再验证该操作是否正确。 这是由MBIST和scan清除功能实现的。 scan清除引擎只能由PMU和CSU处理器通过直接接口进行控制，其他处理器如果要请求启动任何特定的can清除引擎都必须通过SCAN_CLR_REQ寄存 Explore the xilsecure library on Xilinx Wiki for comprehensive details on its functionality, features, and implementation guidelines for developers. These options are available under CSU Tamper Response settings on the Advanced Configuration page. reset = XLNX_CSU_DMA_INT_R_MASK \ + }, { \ Xilinx Embedded Software (embeddedsw) Development. In use cases where you want two BIN files - stable and upgradable, PMU firmware can. It also contains an associated ROM, a small private RAM, and the necessary control/status registers required to support all secure operations. PMU Firmware can be loaded by either FSBL or by CSU BootROM (CBR). The CSU_DMA is a 2 channel simple DMA, allowing separate control of the SRC (read) channel and DST (write) channel. In this configuration stage, the BootROM (part of the CSU ROM code) interprets the boot header to configure the system and load the processing system’s (PS) first-stage boot loader (FSBL) code into the on-chip RAM (OCM I am currently trying to implement a bare-metal application for Zynq MPSoC that is supposed to reconfigure the PL. For Known Issues related to the FSBL and CSU Boot Rom, Please check (Xilinx Answer 65467) In order to determine this, program an image with FSBL debug prints enabled. The hardware in use is zu11eg. On ZynqMP, the CSU_DMA is present inside CSU (Configuration Security Unit) module which is located within the Low-Power Subsystem (LPS) internal to the PS. This set of tools provides you with everything you need to simplify embedded system design for a device that merges an SoC with an FPGA. Secure boot in Zynq® UltraScale+™ MPSoCs is accomplished by combining the Hardware Root of Trust (HWRoT) capabilities with the option of encrypting all boot partitions. However U-Boot is running at EL2 Non-Secure and cannot access the secure register directly. This additional handshake step is required in boot scenarios where FSBL is started by CSU. It shall use the CSU DMA to copy the (unencrypted) bitstream from DDR to the PCAP interface. The Xilinx UltraScale MPSoC architecture, the Vivado Design Suite and additional design abstraction tools combine to break system-level processing bottlenecks through multiple technology breakthroughs.

The FreeRTOS Application works fine when I run it from JTAG (with the application's PMUFW). How can I access it from U-Boot? nterrupts can be either edge triggered or level triggered. The QSPI has a dedicated region for maintaining persistent boot state registers and the associated boot image offsets. Hi <p></p><p></p>When booting a Zynq Ultrascale\+ device from SD card the question arose<p></p><p></p>Once the CSU Bootrom execute and try to access the SD card to load FSBL ( assuming everything else is set up correctly ), If access failure occur ( example SD card not ready yet ) will the Boortom retry to access for several attempts or exit Where can find the detail description or documentation about the ERROR associated the BOOT. Before the CSU_DMA transfer to the PCAP, the xilfpga library resets the PL and the PS_INIT_B is set to a low level. The Xilinx® Zynq®-7000 All Pro-grammable SoC supports confi uration of the interrupt either way, a WHY USE AN INTERRUPT- DRIVEN APPROACH? sors and the like) that will at times require process-ing.
