Device Frozen After Flashing 0.46 Code

[maxim-sm]

I have the EINK290 (Tindie order: #246050). It is a great device and thank you for that!
Unfortunately I have an issue flashing the code in this repository on the device.

Problem Description: After flashing the device with the code it stops working. The screen is stuck on the last thing that was drawn on it and the LED doesn't show any sign of life.

Steps to reproduce:

1. Install Arduino IDE
2. Configure it as described in the README
3. Flash with an ST-Link V2 device (probably a clone)

Device Details:

• Device Variant: NRF52840
• Buzzer: No
• AAA Batteries: No
• Light Sensor: No

Additional Information:
I'm a newbie and never worked with MySensors and have very little experience with programming hardware.
I used the Serial.println and the blinkLed function from your code to determine that the code enters the before() and happy_init() functions until getting stuck in the first if condition.
if (hwReadConfig(EEPROM_NODE_ID_ADDRESS) == 0) {

I've followed the MySensors code and I think that the code gets stuck at
uint32_t *vpage = VirtualPage.get(NVRAM_MAGIC);

in NVRAM.cpp (line 275 in Arduino/libraries/MySensors/drivers/NVM/NVRAM).

I tested some code snippets that I could find from MySensors and it seems that every code that involves reading or writing to the NVRAM (such as hwReadConfig, hwWriteConfig, getState, etc.) gets the device stuck.

To summarize the flow of the code until getting stuck is:
hwReadConfig(line 4487 in EINK290_1) -> NVRAM.read(line 57 in MyHwNRF5.cpp) -> VirtualPage.get(NVRAM_MAGIC) (line 275 in NVRAM.cpp).

I didn't follow the code further for it is definitely out of the scope of my knowledge.

Additional Things that I Tried:
-Older versions of MySensors (until 2.2)
-Variation of arduino-nRF5 library that can be found on your Github
-Testing on Windows and Linux
-Different "Low Frequency Clock" options
-Different MyConfig.h variations (commenting and uncommenting different options)

Details About my Environment:
-Arduino IDE Version: 1.8.13
-MySensors Library Version: 2.3.2
-ST-Link V2 Device Used: https://www.amazon.com/DAOKI-ST-Link-Programming-Emulator-Downloader/dp/B01EE4WAC8
-IDE Output:

Hello, I just read the letter briefly. Tomorrow I will try to reproduce this problem. In any case, we'll figure it out. Will you tell me you are trying to start a flashed device in the mysensors network or without a network? is there a mysensors gateway? чт, 20 мая 2021 г., 14:18 maxim-sm ***@***.***>:

Thanks a lot for the quick response.

I have a MySensors gateway and the gateway is the only device that I currently have on the network.
I'm very new to the MySensors world and still trying to understand the basics.
It all started with me trying to get the EINK290 to be the first device on the network and work with Home Assistant. I did it by adding the following code which supposedly needed for Home Assistant (as I saw in HA's documentation and a YouTube video I used for help):

#define CHILD_ID 1

And the following to the setup():

Serial.println("Requesting initial value from controller");
request(CHILD_ID, V_STATUS);
wait(2000, C_SET, V_STATUS);

Once these changes didn't work (the device was frozen), I tried to flash the vanilla code from the repo without these additions.
I honestly hope that I didn't screw anything up with this code, although it seems that the device is stuck even before executing any of this.

Sorry to bother with this, but have you had a chance to check if you can reproduce the issue?

[smartboxchannel]

Only today I have the soldered boards of the desired version on my hands, I will try to reproduce them. By the way, your device does not have an external quartz resonator, try to flash the device with the settings in IDE - RC for now

[maxim-sm]

Thanks for the suggestion. Unfortunately I already tried changing it to the RC setting which didn't help.

[smartboxchannel]

https://github.com/smartboxchannel/EFEKTA-EINK290-TEMP-HUM-PRES-WEATHER-MINI-STATION-NRF52/tree/main/CODE/HEX

Try downloading the compiled firmware for now.

This can be done by connecting j-link to the device and opening cmd.

you need to insert a line:

nrfjprog -f nrf52 --program "C:\EINK290_1_52840_RC_ST.ino.hex" --chiperase -r

and press enter.

do not forget to specify the correct path to the hex file

[smartboxchannel]

Thanks for the suggestion. Unfortunately I already tried changing it to the RC setting which didn't help.

Hello, have you tried to flash the device with ready-made firmware? This will allow us to understand where the problem is.

Sorry, not yet. I'm not at home this weekend, but I will test it tomorrow evening once I'm back. Thanks! 🙂

[maxim-sm]

First, thanks again for helping me with this! I really appreciate it.
I flashed the HEX file and it worked perfectly! 🥳 It successfully connected to the gateway and Home Assistant.

I didn't use nrfjprog as I have an ST-LINK device (I read that it isn't compatible). So I used openocd to flash it.
If anyone needs the commands:

$ /opt/openocd/bin/openocd -f interface/stlink.cfg -f target/nrf52.cfg
> init
> halt;nrf5 mass_erase
> program EINK290_1_52840_RC_ST.ino.hex verify reset

Taken from: https://4k2.de/microcontroller/openocd-flashing-nrf52/

Please let me know how can I help you further debug this issue.

[smartboxchannel]

I assumed that by loading the compiled hex file, the device would start. This indicates that my instructions for installing the development environment, boards and libraries are not so good. I'm sure this is the problem. In the coming days, I will update the manual, make it more detailed and ask you to try to reinstall all libraries, edit all files, compile and try to flash the device with the firmware already compiled on your side.
