413 PCB

问答对人有帮助，内容完整，我也想知道答案 0 我在使用 ESP-Prog 在自定义 PCB 上闪存 ESP32-S3-WROOM-1u 时遇到了一个奇怪的问题。当 ESP-prog 串行接头上的 TX 线连接到 ESP32 的 RX0 引脚时，串行输出停止。在 VSCODE 中使用 platformio，串行监视器在 TX0 (ESP32) -> TX (ESP-prog) 或 RX0 (ESP32) -> RX (ESP-prog) 时从 ESP32 接收以下输出：代码：全选 ESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0x3 (RTC_SW_SYS_RST),boot:0x9 (SPI_FAST_FLASH_BOOT) Saved PC:0x403cdc76 SPIWP:0xee mode:DIO, clock div:1 load:0x3fce3808,len:0x1660 load:0x403c9700,len:0xbcc load:0x403cc700,len:0x2fac entry 0x403c9954 I (29) boot: ESP-IDF 4.4.4 2nd stage bootloader I (29) boot: compile time 20:42:44 I (29) boot: chip revision: v0.1 I (31) boot_comm: chip revision: 1, min. bootloader chip revision: 0 I (38) boot.esp32s3: Boot SPI Speed : 80MHz I (43) boot.esp32s3: SPI Mode : DIO I (47) boot.esp32s3: SPI Flash Size : 16MB I (52) boot: Enabling RNG early entropy source...
