This example is a demo project to P/E (Program/Erase) main-area of eFlash.
|
|
> The execute-bin will occupy front area of eFlash,
|
|
as the result P/E the other area of eFlash
|
|
|
|
There are 3-case in this example
|
|
> + word data
|
|
> + half-word data
|
|
> + byte data
|
|
|
|
The execute-flow of every case:
|
|
|
|
+ Erase eFalsh (secotr by sector) and verify word-data is `0xFFFFFFFF` or not
|
|
> If the word-data is NOT `0xFFFFFFFF`, it will stop procedure and log error message
|
|
|
|
+ Program **word/hword/byte-data** to eFlash and verify the result value of eFlash
|
|
> If the data is NOT match, it will stop procedure and log error message
|
|
|
|
It also supports fix/random pattern
|
|
|
|
+ Fix pattern is `0x5A5A5A5Aul`
|
|
+ Random pattern
|
|
> User should modify `CONFIG_USE_RAND_DATA` as below
|
|
> ```
|
|
> // at main.c
|
|
> /**
|
|
> * Use random data as pattern
|
|
> */
|
|
> #define CONFIG_USE_RAND_DATA 1
|
|
> ```
|
|
|
|
If user wants to get more detail message, unmark `CONFIG_MORE_MESSAGE` definition
|
|
|
|
```c
|
|
// at main.c
|
|
/**
|
|
* Get more log message
|
|
*/
|
|
#define CONFIG_MORE_MESSAGE
|
|
```
|
|
|
