我的芯片是
Detecting chip type... ESP32
Chip is ESP32D0WDQ6 (revision 1)
Features: WiFi, BT, Dual Core, 160MHz, VRef calibration in efuse, Coding Scheme None
Crystal is 40MHz
MAC: 30:ae:a4:c0:67:60
Uploading stub...
Running stub...
Stub running...
Manufacturer: 20
Device: 4016
Detected flash size: 4MB
Hard resetting via RTS pin...

我用的是 idf带的样例helloword 使用 idf menuconfig component config 设置 CPU frequency (240Mhz)
buid
-p <port> flash
minicom 连接显示如下

rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:2
load:0x3fff0018,len:4
load:0x3fff001c,len:6684
load:0x40078000,len:13756
ho 0 tail 12 room 4
load:0x40080400,len:4336
entry 0x400806ec
E (69) boot: Chip CPU frequency rated for 160MHz. Modify CPU frequency in menuconfig

但我在160Mhz是正常的显示HelloWorld
想知道 esp32 cpu 是不是有什么版本差别? 还是我的其它地方没配置对的?
