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

@ncollins I've been working on turning an stm32f030f4p6 into a blackmagic probe for a few days now. Hit a wall when the compiled firmware came out to 83kb which is over the 64kb on board. Found someone who shrunk it down so it'd fit, and someone claiming it has another 64kb which can be unlocked. I'm just looking for the patience to get back in there, as this whole thing has been a major ordeal
