FS32K118 code Flash Erasable times

问题:

压力升级测试6W次，开始偶现FLASH擦除失败问题。复现概率1/300

擦除使用库函数 address = const 0x0000e000U,size = const 0x32000U:

出现问题ret不为seccess。

现在急需想寻求帮，flash可编程最大次数为？ S32K-RM.pdf中是否有相关说明，如果有请指出。

谢谢。

uint16_t FlashErase(uint32_t address, uint32_t size) { uint16_t ret = STATUS_SUCCESS; /*关全局中断*/ INT_SYS_DisableIRQGlobal(); /*erase*/ ret = FLASH_DRV_EraseSector(&g_tflashSSDConfig, address, size); if(STATUS_SUCCESS != ret) { INT_SYS_EnableIRQGlobal(); return ret; } // DEV_ASSERT(STATUS_SUCCESS == ret); /* Verify */ ret = FLASH_DRV_VerifySection(&g_tflashSSDConfig, address, size / FTFx_DPHRASE_SIZE, 1u); /*开全局中断*/ INT_SYS_EnableIRQGlobal(); return ret; }

Question:

The pressure upgrade test was conducted for 6W times, and the flash erase failure problem began to occur occasionally. Recurrence probability 1/300

Erase using library function address=const 0x0000e000U, size=const 0x32000U:

When there is a problem, ret is not second.

Now we need help urgently. What is the maximum number of times flash can be programmed? Whether there are relevant instructions in S32K-RM.pdf. If yes, please indicate.

thank you.

Hello @sunxiaoyi,

How many times did you erase the sectors?

Cycling endurance is guaranteed up to 1k cycles.

Daniel
