Hello
it's a E73 2G4M04S1B from EBYTE
When i switch SWDIO and SWCLK, i can see the led of STLink V2 changing from red to blue, but when i try to uplod empty sketch (MyBoardNRF5), i have this error :C:\Users\Sancho\AppData\Local\Arduino15\packages\sandeepmistry\tools\openocd\0.10.0-dev.nrf5/bin/openocd.exe -d2 -f interface/stlink-v2.cfg -c transport select hla_swd; set WORKAREASIZE 0x4000; -f target/nrf52.cfg -c program {{C:\Users\Sancho\AppData\Local\Temp\arduino_build_432557/MyBoardNRF5.ino.hex}} verify reset; shutdown;

n'existe pas ou votre Arduino n'est pas connectée@sancho119 No matter what I tried, I could not unlock the E73 with the STLink.
I had to buy a jlink clone, download a bunch of segger debugging tools, use the segger tools to override the lock flag. After that I could flash the bootloader.

Hi. Are the steps in first post still valid please?
I'm trying without luck to get first nrf52 programmed. I get a weird error"Error resolving FQBN: missing" in Arduino IDE when I try to verify any basic sketch, even blink. Thanks for any thoughts
-
@p359 Which version of Arduino IDE are you using? I was seeing that with 1.8.10, but I ended up downgrading to 1.8.6 to test and it worked.

Hi,
Is it possible to get Serial output in Arduino IDE for nRF52 boards with J-Link OB 7.0? Or do I need a newer programmer? Or maybe I can get it with ST-Link v2/v2.1 somehow?

The answer is actually in the first post.

Thanks, I've seen it before. In my case a programmer is easier solution - I don't know yet how to re-assign TX&RX pins in Arduino on my EByte 52840 module and in specs for that module there is no info about UART connectivity.
Maybe you know how can I re-assign TX&RX pins in Arduino? Then I can solder wires to assigned TX&RX pins and connect them to USB-UART. What I've found is in Forth language ... -
Does anyone know what settings I need to use for this development board with arduino ide?
Ebyte E104-BT5032A-TB
https://a.aliexpress.com/_dT5dMb8It has a cp2102 on board which I have the driver for. I've installed the arduino ide nrf52 board, but I can't find a programmer, board, or any other settings which will let me flash it without a Java exception or a timeout. Maybe I need to set the jumpers differently but there's no documentation on that.
OTA works fine though. -

OTA works fine though.@idanronen this is a UART to BT module, and from what I understand in the documentation the CP2102 is only here to give you access to the serial port of the module, but not to program it ?
To program it you will have to use the SWDIO/SWDCLK pins I suppose, and I'm interested to know if it can be reprogrammed because that would make a tiny NRF52832 module for boards that don't require many IOs.

@Nca78 I feared that might be the case. my task for today was to dig up my st-link and try that, though I hoped I might have done something wrong and the cp2102 can be used to program and not just debug.
That module is pretty cheap and from what I see with the naked eye, you can disconnect the cp2102 with the jumpers so the power consumption might actually be good enough to use as-is.
I'll report back to let you know once I've succeeded -
I tried flashing MySensors onto my nRF52840 Adafruit Feather board but it fails, I opened an issue on GH about it https://github.com/mysensors/MySensors/issues/1424, maybe someone here has any ideas how to get it running on those boards?

@Nca78 no luck with the st-link v2, though i doubt it is related to the board, but rather my inability. i've tried every option in zadig, installed the st-link driver from their website, and nothing works.
i get this in arduino ide:debug_level: 0 0x4000 adapter speed: 10000 kHz Error: init mode failed (unable to connect to the target) in procedure 'program' in procedure 'init' called at file "embedded:startup.tcl", line 473 in procedure 'ocd_bouncer' ** OpenOCD init failed ** shutdown command invoked the selected serial port does not exist or your board is not connected -
With all the NRF52 modules from EBYTE I've tried, the only way I can flash them is over SWDIO, SWCLK, GND, VCC via JLink clone.
And, before flashing is possible, I have to unlock the module by following these directions: https://github.com/micooke/arduino-nRF5-smartwatches/blob/master/nrf52_disable_read_protection.txt
