Hello,
Some news !
i buy a Jlink, and success in erase my nrf52832 with nrf prog, using method of berkseo.Next i try to upload a basic sketch (blink) :
#define MY_RADIO_NRF5_ESB
#include <nrf.h>
#include <MySensors.h>void setup() {
Serial.begin(9600);
hwPinMode(LED_BUILTIN,OUTPUT_H0H1);
}void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}I have this :

LED_BUILTIN corresponds to po17

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
-
Im not sure my flashing with the blackmagic even does anything. The console is unclear:

I just got my first NRF5 running. I'll note how I got it working in case any of you guys still have troubles:
Setup
- OS: Windows 10
- Programmer: STM32 Blue Pill with the Black Magic Probe firmware
- NRF5: EByte E73-TBB dev board with a E73-2G4M0S1B (NRF52832)
- Environment: PlatformIO
Instructions
Load the Black Magic Probe firmware with
stlinkas the probe host onto Blue Pill. You can follow this guide.Connect your new BMP to the NRF52 module:
BMP NRF52 Serial Port 3V3 3V3 GND GND A5 SWDCLK GDB Server B14 SWDIO GBD Server A2 RXI UART A3 TXO UART Note: A2 and A3 are not required for programming. This is how you'd wire up the BMP for "classic" serial debugging. You can use the BMP both for programming and serial communication - no need for a second FTDI module.
Using the GNU Arm Embedded Toolchain, run
arm-none-eabi-gdbin a console and enter the following commands to unlock the NRF52:target extended-remote BMP_GDB_SERVER_PORT mon swdp_scan attach N // N = number of "Nordic nRF52 Access Port" if there are several mon erase_mass detachFrom the two serial ports the BMP provides, you want to use the GDB Server for
BMP_GDB_SERVER_PORTabove. If Windows only provides generic names for both ("USB Serial Device" or something), the one with the lower number should (usually) be the right choice. If not, try the other one.Windows users also must prefix the port with
\\.\if the number is double-digit, e.g.\\.\COM13.Now you can start uploading sketches the usual way. Here's my minimal PlatformIO config:
[env:nrf52_dk] platform = nordicnrf52 board = nrf52_dk board_build.variant = generic framework = arduino upload_protocol = blackmagic lib_deps = 548 ; MySensorsAnd a minimal test sketch for MySensors:
#include <Arduino.h> #define LED 17 #define MY_RADIO_RF24 #define MY_RADIO_NRF5_ESB #define MY_NODE_ID 182 #define SKETCH_NAME "NRF52 Test" #define SKETCH_VERSION "0.1" #include <MySensors.h> #define CHILD_ID 1 MyMessage msg(CHILD_ID, V_VAR1); void presentation() { sendSketchInfo(SKETCH_NAME, SKETCH_VERSION); present(CHILD_ID, S_CUSTOM); } void setup() { pinMode(LED, OUTPUT); } void loop() { static uint8_t num; send(msg.set(num)); ++num; digitalWrite(LED, HIGH); wait(5000); digitalWrite(LED, LOW); wait(5000); }Works like a charm so far! Now, if you please excuse me, I have a whole new microprocessor family to explore. Fun times!
