通过认证后,就会把镜像从Flash加载到OCM(On-Chip Memory),然后接下来的启动过程就由FSBL控制。 Zynq的启动还分为安全模式和非安全模式,这个使用用户在前面所提到的头部信息中设置的。除了JTAG方式为,不管以何种模式启动,都是由PS部分的代码来完成PS和PL部分的配置。所以,对于Zynq-7000器件,不能从PL端直接进行启动配...

59518 - Zynq-7000 SoC: QSPI boot time consideration with larger QSPI memory Description When booting a Zynq device with a large (> 16MB) QSPI, such as on the Zedboard, boot times are not improving when a fast QSPI clock ( over 40 MHz) is programmed. When the user changes the FSBL def...
In Zynq-7000 AP SoC, the JTAG port is used to load software and the bitstream, load the AES key, control information, and for debug・ If not disabled, JTAG ports can be used by an adversary to insert malware, and read configuration memory and registers・ The JTAG ports must be ...

Bitstream (BIT) and block memory map (BMM) data are downloaded to the Zynq-7000 AP SoC to load any custom design logic into the PL, but this step can be omitted when running applications that require only the PS. Create an SDK configuration run to download and run the application ELF ...
