EG800AKCN91LC模组外挂了一颗FLASH,2M，编译成功后使用aboot下载提示如下

您好，
combined_flash_size_in_mb = 0MB ← 检测到flash大小为0MB
Manufacturer ID: 0x20, Device ID: 0x5016 ← 第一次能读到ID（XM25QU32C，4MB）
Spi init error: 1380! ← SPI初始化错误码1380
Manufacturer ID: 0xFF, Device ID: 0x6015 ← 第二次读ID失败（0xFF=通信异常）
[spi_nor_flash_probe] failed! ← flash探测最终失败
可能是QSPI 引脚配置错了，请查看一下配置是否正确

[poq]

你好，读取ID是正确的：id是EF

可以在JSON文件添加W25Q16JWXHIQ，添加后如果还是无法烧录，那就说明不支持这颗flash

[poq]

SPI_NOR_2MB_B64KB_S4KB_P256.json文件里加上了FLASH的 信息

{

  "name": "W25Q16JWXHIQ",

  "manufacturer": "WinBond",

  "vendorId": "0xEF",

  "deviceId": "0x6015"

},

下载日志文件私聊您了。

更换开发板上带的FLASH，也下载不进去，日志文件也发您了

本问题实际上是Flash和aboot速度不匹配问题

[poq]

问题已经解决，整理了一下思路，方便有需要的人自取
