Zigbee2mqtt: Alt Firmware Flashing -> use CCLoader instead of CCLib

[Domochip]

I tried CCLib to flash firmware, but got too much problems and flashing time took many hours

I discovered that using CCLoader that works very fine and flash took a few minutes...
https://github.com/RedBearLab/CCLoader

I needed to use Z-Stack-Firmware .hex file, convert it using hex2bin then flash it using CCLoader_x86_64.exe

[Koenkk]

Great, I think there is still a usecase for CCLib as CCLoader only seems to support windows.

Could you make a pr to update the documentation? (https://github.com/Koenkk/zigbee2mqtt/blob/master/docs/information/alternative_flashing_methods.md#via-arduinoesp8266)

[momo90-2]

Is ccloader working for a cc2531 or cc2530 stick?
Is it necessary to convert the hex file via hex2bin or can the bin file be used which is provided in the zip archives here https://github.com/Koenkk/Z-Stack-firmware/tree/master/coordinator?

Using hex2bin with the hex files provided in the zip files causes an error.
Edit: using srec_cat.exe to convert the hex to bin file works and I think sorts the records in ascending address order (maybe because of that hex2bin didnt work). Havent yet tried CCloader to upload...

[momo90-2]

I have testet CCloader but it didnt work for me (although it should work according to the datasheet of cc254X and cc253X). What i did:

1. used srec_cat.exe to convert the .hex file from the archive from here https://github.com/Koenkk/Z-Stack-firmware/tree/master/coordinator/CC2531/bin to a bin file. srec_cat.exe warned that the hex is not in ascending address order and reordered it.
2. connected the cc2531 like described here https://github.com/RedBearLab/CCLoader, checked and measured the connection about 5 times. Connection was ok.
3. tried ccloader.exe and ccloader_x86_64.exe.
4. tried a Arduino and (without logic level converter) and a nodemcu (changed the pin definitions in the sketch)

ccloader connected to the arduino but, didnt find the chip. Error message "no chip detected", which means that ccloader cant communicate to the chip via DD. Apart from that ccloader said that the bin is corrupt. Havent tried the files from here https://github.com/mtornblad/zstack-1.2.2a.44539/tree/master/CC2531 yet. Maybe it is a power problem. Eventually i am going to power the cc2531 via usb instead of 3,3. Could also be the problem mentioned here https://github.com/Koenkk/zigbee2mqtt/issues/78#issuecomment-450737978

Possible solution/to be tested:

1. using Arduino Uno with logic level converter
2. using hex from here https://github.com/mtornblad/zstack-1.2.2a.44539/tree/master/CC2531
3. power cc2531 via usb

I got mine to flash without issue with CC_Loader, and it was much faster about 2-3 minutes.

I created PR 9 for this.

[Koenkk]

PR is merged, thanks all.

[AS137430]

@Nomsplease : you flashed the SBL .bin version of the firmware with CCLoader from here? By the way, CCLoader has Linux/Mac version as well. This fork works for ESP8266.

[Nomsplease]

@AS137430 Yes that is the firmware in the updated documentation. I tested this with a Uno/Windows. If you can get it to work on Linux/Max and an ESP reliably please update that documentation with any other steps necessary. It never hurts to have more options. :)

[AS137430]

@Nomsplease: Thanks for your clarifications on the bin file used. I already flashed my first CC2531 with the first Arduino/ESP method. But I am waiting for delivery of the second CC2531 (which is taking a while..) and will definitely try the CCLoader method since it is much faster and report back if I am successful with the ESP8266 on Linux.

[krikk]

i tried to flash my cc2531 with this new method (useing ESP8266, wemos D1 r2) and it seemed to work:

but after "flashing" the stick seems to be dead... the led does no longer flash and i do not get a device if i connect it to the pc/raspberrypi :(

...re-flashing with the "old" alternative flashing method did revive the cc2531 stick, now it is blinking again :)

Is the SBL bin firmware supposed to be flashed only through SerialBootLoader??

[kianusch]

After playing around a bit, a few thoughts ...

Using the bin file from zigbee2mqtt repository will not work.
But you can convert the hex file to a bin file - under linux the command is:

$ objcopy --gap-fill 0xFF --pad-to 0x040000 -I ihex CC2531ZNP-Prod.hex -O binary CC2531ZNP-Prod.bin

$ ls -lt CC2531ZNP-Prod.*
-rw-rw-r-- 1 kianusch kianusch 262144 Mar 2 13:59 CC2531ZNP-Prod.bin
-rw-r--r-- 1 kianusch kianusch 697099 Jan 29 19:23 CC2531ZNP-Prod.hex

objcopy is part of binutils package.

The resulting file can be passed to CCLoader for flashing:

$ /opt/CCLoader/SourceCode/Linux$ ./a.out /dev/ttyACM0 /tmp/CC2531ZNP-Prod.bin 1

If CCLoader gets stuck at "Request sent already! Waiting for respond..." press CTRL-C and try changing the last parameter from 1 to 0 ... (also check your wiring)

$ /opt/CCLoader/SourceCode/Linux$ ./a.out /dev/ttyACM0 /tmp/CC2531ZNP-Prod.bin 0

This will set DTR to "off" during initialization phase.

Also - I adapted my CCLoader.inc and changed the pinout to have the pins in a row:

int DD = 2;
int DC = 3;
int RESET = 4;

This makes wiring more easy.

Hope this helps.

[AS137430]

@kianusch: Thanks for the detailed instructions especially the objcopy command. Is that an Arduino Pro Micro you are using? You are using GND and pins 2-4 from what I can make out for the picture. How is CC2531 powered?

[kianusch]

Yep - this is a Pro-Micro, I know, I soldered the pins on the wrong side :)
But Arduino UNO works as well.

And - yes:

Arduino -- CC2531

• GND -- GND [PIN 1]
• 3.3V -- VDD [2]
• Pin 2 -- DD [4]
• Pin 3 -- DC [3]
• Pin 4 -- RESET [7]

CC2531 can be powered via VDD (PIN1) - I tried 3.3V and 5V - both worked - but I'm not sure, if all CC2531 sticks are 5V save.
As an alternative CC2531 can also be powered via USB - after plugging in the Arduino, wait a few second and than plug in the CC2531. Be sure to use the correct USB device, the one where Arduino shows up, when starting CCLoader.

[AS137430]

@kianusch : Thanks. Will you raise a PR to update the wiki https://www.zigbee2mqtt.io/information/alternative_flashing_methods.html?
@Koenkk : There are now more details on the CCLoader method for flashing. Please take a look, thanks.

[kianusch]

Sorry - I have no idea how to raise a PR.
I actually don't now what you mean by PR. :/
Priority?

@kianusch : A Github Pull Request (PR). Similar to https://github.com/Koenkk/zigbee2mqtt.io/pull/9.

If you need Windows version of objcopy, you can try MinGW's binutils includes objcopy.exe. Alternative: Win-builds's binutils

For those with limited time available: I can confirm that the CCLoader route works in a flash (;-)). Spend a day on the CCLib route but couldn;t get to reliable uploading, although the communication through the chain worked as such. Rather than an Arduino, I used a Jeenode which works with 3.3v off the shelf.

I haven't tried programming via ESP myself ... but you might have a problem with the pin numbering ...

Maybe this helps:

[AS137430]

Does this help?

[jackwilsdon]

I can confirm that I needed to use @kianusch's objdump command to get CCLoader to flash correctly on macOS - trying the normal .bin from the repository causes the device to not work, flashing the objdump'd bin works fine.

[Hedda]

FYI, also see https://github.com/Koenkk/zigbee2mqtt/issues/3694 for another alternative method of firmware flashing.
