MYSBootloader 1.3pre2 testing

Anduril

@pku if your keys are in the sketch everything will work for signing.
#define MY_SOFT_HMAC_KEY XXX... //signing key
#define MY_AES_KEY XXX... // if you use encryption
Of course if you want to use whitelisting then you need to compile each node sketch separately with it's serial.

but that would give a listener your full MY_SOFT_HMAC_KEY and signing would be useless in future. Therefor it is better to write the key in eeprom with cable and later only update firmware without key via OTA.

@Anduril

I agree, keys located in sketch can be used as workaround only, because the security is broken.
But I'm interesting in key located in EEPROM. How it is work during flashing? If Clear EEPROM fuse is not set then everybody can take my outside node, put his own firmware and it will work with keys from EEPROM. It is again a security issue (of course he must have physical access to my node).
I thing it should work with this scenario:

reguest for new firmware
copy key, serial and rsa into RAM
flash new firmware (with fuse clear EEPROM)
copy key, serial and rsa back into EEPROM

What do you thing?

Anduril

For a node that is physically accessable it is realy hard. First: does this node needs signing? For sensor data you don't need in most cases. Maybe you should use the hardware chip, there you can't read out the key and if it was locked you also can't change it.
If you still need to use softsigning you could use whitelisting and revoke the whitelist-entry in case of corruption.

Hello,

I am trying to use MYSController with MYSBootloader 1.3pre2 to reassign a node's ID, and I cannot make it work.
I've tried to check/uncheck the Auto ID toggle/tried to use the MYSBootloader CMDs/Assign ID and setting a new one to no avail.

After that, when it reboots, the node reask for it's firmware, and MYSController re-uploads it, but the node keeps the old ID from the EEProm. (note that the sketch don't hardcode the node's ID).

I'd like to keep the ID management free (i.e. do not hardcode all my node's IDs of course)

How can I do that?

Hi! Great work!
I have a small question: How does your Bootloader know which channel to listen on?

pku

@JamesT42
Hi, it is hardcoded within the bootloader: nRF24 (Channel 76, base address 0xA8A8E1FC00, data rate 250kbs)

tekka

@jmkhael Bootloader commands have been removed due to size constraints (see initial post). If you want to change the node ID you can send a C_INTERNAL / I_ID_RESPONSE / <new ID> message to an actively listening node.

tekka

@JamesT42 Thanks. As @pku pointed out, this is hardcoded. With the final release of MYSBootloader and its source code, everybody will be able to adjust settings and recompile the bootloader as needed.

jmkhael

@tekka : fair enough, i should read better next time :)
i'll try the way you suggest. thank you.

kleinerDrache

hi tekka
I had to change the channel of the NRF from 76 to 0 here because of massive disturbances . Unfortunately, no OTA works now. Is it possible to create a modified bootloader that works with 0 instead of 76? Sorry for the bad english it is translated with google.

Lorenzo

Hi, thank for the great work.
I also use a different Channel, in fact I have 3 area with 3 differents Channels.
Do you have a plan about source code release date ?

techRH

Is there a way to debug the bootloader should it print debug information and how to see this?

Hi,
I just start to test this bootloader...
I use an ATmega328p on breadboard with no external clock, with nRF24 and somes sensors.
Firmware Upload (by usbasp) and Run is ok, Send/Receive Data is ok too , but when I ask a reboot (with MYSController 1.0.0beta), my node enter in sort of strange start loop...
My Fuse settings :

bootloader.unlock_bits=0x3F
bootloader.lock_bits=0x0F
bootloader.low_fuses=0x62
bootloader.high_fuses=0xDA
bootloader.extended_fuses=0x07

Node debug Trace :

.....

The "Startiþ" text is the first char of the first text printed by bootloader at start : "Starting sensor....."
Have you an idea ?

Thanks

tekka

Please provide additional information such as library version, full debug log of your GW and node. Which bootloader/version are you using?

Tetnobic

@tekka Thanks for you response
For gateway :
Raspberrry PI Gateway in Ethernet mode

For Node :
I use bootloader : MYSBL13pre_atmega328_1Mhz.hex
Inital Sketch do nothing :) :

Starting sensor (RNONA-, 2.0.0)

Your node is running MySensors 2.0.0 (your GW is at 2.0.1, please consider updating), also, there is no sign of MYSBootloader in your GW log - please double-check if you followed the correct procedure.
One more thing: the startup message indicates that you enabled OTA firmware features (RNONA-) - this is not required with MYSBootloader.

Please have a look at @scalz's OTA guide for additional information.

Tetnobic

@tekka Thanks for your response
What are the sign of MYSBootloader in GW log ?
Can I also see any sign of MYSBootloader in Node Log ?

I remove OTA firmware features, I now have :

Starting sensor (RNNNA-, 2.0.0)

but same problem, after receive reboot message I have a "StartiStartiStartiStartiS...." loop :(:(

tekka

@Tetnobic No, you won't see anything in the node log - but in the GW log you should see somehting like:


1;255;4;0;0;64000200C803948D0105

Tetnobic

@tekka Hi, I found my mistake ! You were absolutely right when you said there is no sign of MYSBootloader in my GW log...
But now I know why :) :
I use an USBasp Programmer with Arduino IDE for upload my bootloader and my sketch..., and I mistakenly thought that when I upload bootloader then sketch, it keep bootloader.....but NOT, it overwrite bootloader :(
I fix it by uploading the xxx.with_bootloader.hex file generated by Arduino IDE when compile.

Sorry for the inconvenience and thank you for your help
