esp32s3各种问题，希望有技术人员关注以下

[末班车上的乘客]

1）芯片选的是内置的8M版本，初始化过程显示发现8M，程序运行后打印出来缺不到1M。加了几个应用之后，现在连lcd单buf都分配不到

2）下载程序总是识别，bin文件大一点的总是失败，三分之一的时间都用在下载程序了。为什么这个口下载这么慢，有没有usb模式

您好：

1、软件使用的 Flash 大小取决于工程使用的分区表设置和软件配置中的 Flash Size 设置。如下：

Serial flasher config → Flash size

esp-idf SDK 中对应的系统分区表文件参见：https://github.com/espressif/esp-idf/tr ... tion_table

如下：

每个工程都有对应的分区表文件设置，在 menuconfig 的 Partition Table → Partition Table 路径下，如下：

2、 ESP32-S3 支持使用 UART 或 USB 管脚下载固件，对应说明参见：https://blog.csdn.net/Marchtwentytwo/ar ... /121169467?

如果使用 ESP32-S3 的 UART0 管脚下载固件固件速度慢的话，可以尝试增加下载波特率，例如使用如下指令：
