For initial deployment of the firmware a few preparation steps are required, which
|
||
|
|
have to be done once.
|
||
|
|
|
||
|
|
1. Get the files ufconv.py and uf2families.json from the micropython/tools directory,
|
||
|
|
e.g. at https://github.com/micropython/micropython/tree/master/tools.
|
||
|
|
|
||
|
|
2. Get the NXP program sdphost for your operating system, e.g. from
|
||
|
|
https://github.com/adafruit/tinyuf2/tree/master/ports/mimxrt10xx/sdphost.
|
||
|
|
You can also get them from the NXP web sites.
|
||
|
|
|
||
|
|
3. Get the UF2 boot-loader package https://github.com/adafruit/tinyuf2/releases/download/0.9.0/tinyuf2-imxrt1010_evk-0.9.0.zip
|
||
|
|
and extract the file tinyuf2-imxrt1010_evk-0.9.0.bin.
|
||
|
|
|
||
|
|
Now you have all files at hand that you will need for updating.
|
||
|
|
|
||
|
|
1. Get the firmware you want to upload from the MicroPython download page.
|
||
|
|
|
||
|
|
2. Push and hold the "Boot" button, then press "Reset", and release both buttons.
|
||
|
|
|
||
|
|
3. Run the commands:
|
||
|
|
|
||
|
|
```
|
||
|
|
sudo ./sdphost -u 0x1fc9,0x0145 -- write-file 0x20206400 tinyuf2-imxrt1010_evk-0.9.0.bin
|
||
|
|
sudo ./sdphost -u 0x1fc9,0x0145 -- jump-address 0x20207000
|
||
|
|
```
|
||
|
|
Wait until a drive icon appears on the computer (or mount it explicitly), and then run:
|
||
|
|
```
|
||
|
|
python3 uf2conv.py <firmware_xx.yy.zz.hex> --base 0x60000400 -f 0x4fb2d5bd
|
||
|
|
```
|
||
|
|
You can put all of that in a script. Just add a short wait before the 3rd command to let the drive connect.
|
||
|
|
|
||
|
|
4. Once the upload is finished, push Reset again.
|
||
|
|
|
||
|
|
Using sudo is Linux specific. You may not need it at all, if the access rights are set properly,
|
||
|
|
and you will not need it for Windows.
|
||
|
|
|
||
|
|
Once the generic boot-loader is available, this procedure is only required for the first
|
||
|
|
firmware load or in case the flash is corrupted and the existing firmware is not functioning
|
||
|
|
any more.
