描述
The 502 Loco™ is the most cost effective way to generate a high-quality, high-frequency clock output and a reference from a lower frequency crystal or clock input. The name LOCO stands for Low Cost Oscillator, as it is designed to replace crystal oscillators in most electronic systems. Using Phase-Locked Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 160 MHz. Stored in the chip's ROM is the ability to generate six different multiplication factors, allowing one chip to output many common frequencies (see table on page 2). This product is intended for clock generation. It has low output jitter (variation in the output period), but input to output skew and jitter are not defined or guaranteed. For applications which require defined input to output skew, use the 570B.

rzg2l M33编译烧入问题
NPE doesn’t be able to flash the M33 using JTAG.The SOM on the DemoBoard is programmed with the image obtained from the SDK rzg2l-yocto-sdk3.0.5 integrating the multi-os part that I get this type of error.

e2studio 开发 ra 项目时，每次编译都是全编译。
如图所示，每次点击 build project，都是全编译，即便工程什么都没有改动，连续按 build project，也每次都是全编译，太花时间。 现在用的 e2studio 版本 ...
