OTA 固件太大会更新失败

[WuWenchang]

OTA 失败！！
旧固件大小是1.9mb，新的固件也是1.9mb。
分区的情况是：
# Name, Type, SubType, Offset, Size, Flags
nvs, data, nvs, 0x9000, 0x6000, ,
otadata, data, ota, 0xf000, 0x2000, ,
phy_init, data, phy, 0x11000, 0x1000, ,
config, data, nvs, 0x12000, 0xEE000, ,
factory, app, factory, 0x100000, 0x400000, ,
ota_0, app, ota_0, 0x500000, 0x400000, ,
ota_1, app, ota_1, 0x900000, 0x400000, ,
user, data, nvs, 0xD00000, 0x200000, ,
flash_tone, data, 0xff, 0xF00000, 0x100000, ,

下面是出错的信息。

报错的信息是内存申请失败，在出错前后有打印看内存的情况，应该是充足的啊，不知道为什么就出错了呢。 工程中有voip的功能，整个工程生成的固件有1.9mb，不要VoIP的功能，生成的固件大概在1mb。如果新固件用1mb的，更新是成功的，用带VoIP功能1.9mb的会更新失败。

大佬方便问下，你开始写入数据的时候都正常么，我一写入数据就会发生系统重启

[alexmyyyyyy]

W (53) boot.esp32s3: PRO CPU has been reset by WDT.
W (58) boot.esp32s3: APP CPU has been reset by WDT.
大佬我是写入数据就系统重启，报看门狗超时，可是已经用esp_task_wdt_deinit(); 指令禁止了
不知道为什么
