Linux and EC200U

[0x7a657573]

I want to use your platform to develop firmware for EC200U under Debian Linux. I set up VScode + PlatformIO and installed your platform into PlatformIO and use the blink example for a test with a little change in line 19 because I connected LED into GPIO_19 :).

#define BLINK_GPIO GPIO_19

the project compiles without error and warning

No dependencies Building in release mode Checking size .pio/build/ec200u/firmware.elf Advanced Memory Usage is available via "PlatformIO Home > Project Inspect" RAM: [ ] 1.0% (used 5408 bytes from 524288 bytes) Flash: [ ] 2.4% (used 25348 bytes from 1048576 bytes)

when trying to upload I got the error ERROR: Unable to find device.. I watched dmsg log and find the EC200U Bootloader port in /dev/ttyACM0

[22114.673793] usb 2-3: USB disconnect, device number 46 [22115.174325] usb 2-3: new full-speed USB device number 47 using xhci_hcd [22115.342761] usb 2-3: not running at top speed; connect to a high speed hub [22115.355495] usb 2-3: New USB device found, idVendor=0525, idProduct=a4a7, bcdDevice= 0.00 [22115.355502] usb 2-3: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [22115.364440] cdc_acm 2-3:1.0: ttyACM0: USB ACM device

for this issue, I change line 188 of rda8910.py from if "SPRD" in port.description: to if "SPRD" in port.description or 1==1: with this change, I can bypass check SPRD string into a port description, after that, I can upload firmware into EC200U.

Searching for USB Port...

but nothing is happening!

You need to update device core for this. I have just made all core files available for flashing, use the one which applies to you. https://github.com/waybyte/logicrom_core

You need to register your device @ https://waybyte.in/devices/register for logicrom to work.

Let me know if you still face any issue.

Thank you for your replay my module part number is EC200U-EU and I tried uploading the core file(.pac) with QFlash 5, core uploaded without a problem. after that, I tried uploading the blink program, program uploaded without problems like in the past but not work again.

Please follow steps mentioned here: https://github.com/waybyte/platform-logicrom#get-free-personal-license

On USB you have 3 ports: Port 0: Application console Port 1: AT command Port 2: AP debug

Later check on console (uart/usb) with at command if firmware is flashed successfully. "ATI" check if network is fine: "AT+CEREG?" "AT+CSQ"

Thank you I register on your website and register my EC200U IMEI and got UID for that. in my hardware with the command getlic and UID finally, I think activate the device! in sysinfo from terminal of device I got:

Library Version: 7.2.0 f805795 - Build Nov 19 2022 20:10:10 Core firmware: Logicrom_v0.1.0-gbba2fe73 SDK Version: LOGICROM_SDK_V0.9.7

If you can access console then probably everything is working fine. You can update your SDK and platform both. current release is 0.9.8
