ESP32-WROVER-E无法正常写入固件的原因？

我自己使用esp32-wrover-E的模组做了块板子，现在上电后ESP32一直往外发invalid header，模块是新的，ESP32用的是ESP32-WROVER-E

rst:0x10 (RTCWDT_RTC_RESET),boot:0x1b (SPI_FAST_FLASH_BOOT)
invalid header: 0xffffffff
invalid header: 0xffffffff

现在问题是我无法正常写入固件

我短接了gnd和io0 io2后 串口显示
rst:0x10 (RTCWDT_RTC_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
waiting for download

再reset重置EN后显示
rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
waiting for download

此时我的开发板已经可以正常写入固件了，但我做的板子却会无法连接，显示

我想知道写入固件还有什么是我没有注意的事项么，stripping的引脚里 io0 io2我应该都设置对了 才会正常出行下载模式的串口输出吧，还有其他需要注意的么，或者是由于模组是新的，第一次写入固件有什么特殊的操作要执行？麻烦各位大神指导下，辛苦了
