IWR1843: ldoBypassEnable的影响

Part Number: IWR1843


板卡修改为LDO=00,使用工程C:\ti\mmwave_industrial_toolbox_4_10_0\labs\Out_Of_Box_Demo(工程配置ldoBypassEnable=3),不能工作

rlRfLdoBypassCfg_t gRFLdoBypassCfg =
{
.ldoBypassEnable = 3, /* 1.0V RF supply 1 and 1.0V RF supply 2 */
.supplyMonIrDrop = 0, /* IR drop of 3% */
.ioSupplyIndicator = 0, /* 3.3 V IO supply */
};

板卡修改为LDO=00,使用工程C:\ti\mmwave_automotive_toolbox_3_6_0\labs\lab0007_medium_range_radar(配置为rfLdoBypassCfg->ldoBypassEnable = 0x03;),可以正常工作

造成此的原因是什么,是outbox工程内对LDO做了什么其他的处理吗,想要知道关于此的原因
