Expected result
|
||
|
|
===============
|
||
|
|
Use the provided shell commands, to read and write pages from/to the MCU's
|
||
|
|
internal flash memory. For altering the data in a flash page, use a sequence
|
||
|
|
similar to this:
|
||
|
|
- read some page from the flash, this will load this page into a local buffer
|
||
|
|
```
|
||
|
|
read 100
|
||
|
|
```
|
||
|
|
- edit the contents of the local buffer, here we write 'Hello_RIOT' to position
|
||
|
|
100
|
||
|
|
```
|
||
|
|
edit 100 Hello_RIOT
|
||
|
|
```
|
||
|
|
- write the local buffer to any target page in the flash. CAUTION: if you
|
||
|
|
override any page, that contains program code (or even the interrupt vector),
|
||
|
|
you will most like encounter hard faults and crashes which can only be fixed
|
||
|
|
by re-flashing the node...
|
||
|
|
```
|
||
|
|
write 100
|
||
|
|
```
|
||
|
|
- check if the contents were written
|
||
|
|
```
|
||
|
|
dump 100
|
||
|
|
```
|
||
|
|
- now power off the node, wait a bit and power it back on. The contents of the
|
||
|
|
page written previously should still be there
|
||
|
|
|
||
|
|
What else to check:
|
||
|
|
- Erase a page with previously known contents, to make sure the erasing works
|
||
|
|
- also check the pages before and after the targeted page, to see if the page
|
||
|
|
size is correct, and that you are only erasing the actual page and not any
|
||
|
|
parts of the neighboring page.

This test provides you with tools to test implementations of the `flashpage`
|
||
|
|
peripheral driver interface.
