接线方式dp dm gnd 连pc usb
焊接好上电之后 连接上usb之后 usb 串口一直打印
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
并且不断重启

按住CHIP_PU 按键 和 GPIO0 按键(均为下拉)然后使用flash download tool 下载 bin文件LOG如下
Uploading stub...
Running stub...
Stub running...
Changing baud rate to 115200
Changed.
NO XMC flash detected!
SPI_BOOT_CRYPT_CNT 0
SECURE_BOOT_EN False
Compressed 15040 bytes to 10333...
Compressed 3072 bytes to 146...
Compressed 1023376 bytes to 335558...

is stub and send flash finish

使用vscode+pio 下载 LOG如下
CURRENT: upload_protocol = esptool
Looking for upload port...

A serial exception error occurred: Cannot configure port, something went wrong. Original message: FileNotFoundError(2, '系统找不到指定的文件。', None, 2)
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

flash download tool 那个截图显示是完成,这个没有成功吗?现在直接用 UART0 看 log 有吗?你试试用 UART0 方式下载能成功吗?电流有满足 500 mA 的最低要求吧?
