[已解决] 关于4.4.2版本boot打印的疑问

[linshc]

今天刚更新的4.4.2，编译程序下载固件时，发现多了这几句的打印。请问一下，这是在检查什么配置？

你是否直接烧录的第三方的 boot bin？是否在烧录时设置了 mode 或 size？

[linshc]

没有烧入第三方的bin，我是直接下载的IDF-4.4.2.zip。替换了IDF-4.4.1后，重新配置了环境。mode是什么mode,这个我没有修改应该是默认的，size是指flash_size吗?改成了8M

你是如何烧录固件的？正常的话，直接 idf.py flash 是不会出这样的问题的。

[linshc]

使用vscode里面的ESP-IDF插件下载的

[ESP_Gargamel]

可能的原因是你 menuconfig 里 flash 的参数配置和烧录时不一致，比如 menuconfig 配了 4MB，但烧录时选择了 8MB，导致烧录时改写了 boot bin 的 header，从而导致对 boot bin 的校验不通过。

Code: Select all

I (45) boot.esp32s3: Boot SPI Speed : 80MHz
I (50) boot.esp32s3: SPI Mode       : DIO
I (55) boot.esp32s3: SPI Flash Size : 8MB

你看下你 menuconfig 里对 flash 的设置，然后看下 IDF 插件里对应的配置。

[linshc]

你好，正如你所说，menuconfig里面的配置和实际flash大小不一样，就会造成这个错误。比如：flash实际大小为8M，但menuconfig中设置flash为4M，编译、烧入完就会造成这个错误。在IDF-4.4.1版本中，这样配置不会有这个提示。
感谢您的解答，以后配置flash时，按照实际的来选择就好了。因为之前跑例程时，会忘记修改内存，运行时，没有上述的提示。

OK，如问题已解决，请修改标题，前面加上 “[已解决] ”。
