Currently seeing the same issue here, with a project moved from 3.5.19. Diving into it too to see if i can find the cause

Post by rabaggett on CODESYS control for Raspberry Pi 64 SL errors ^{CODESYS Forge talk (Post)}
Hi, I am trying to create a project using a raspberry pi, I have added the modules for the Pi and MCP3008. I have encountered som errors that I don't know how to track down. 1. The GPIOs give preprocessor errors, but I read that this does not prevent compiling. This seems to be true. I can build the empty project with no errors. 2. After adding a SPI master and MCP3008, the preprocessor errors double, but seem similar and the project again builds with no errors. 3. I add a DUT and GVL, with a function, and I get the following errors. They remain even if I delete these things. ------ Build started: Application: Device.Application ------- Typify code... [ERROR] crr: C0032: Cannot convert type 'Unknown type: 'ADR(GVL_Io_17160064_c083_41f8_9e53_208be7537753_HPS_7.Io_17160064_c083_41f8_9e53_208be7537753_HPS_7)'' to type 'POINTER TO IoConfigParameter' [ERROR] crr: C0077: Unknown type: 'GVL_Io_17160064_c083_41f8_9e53_208be7537753_HPS_7.Io_17160064_c083_41f8_9e53_208be7537753_HPS_7' [ERROR] crr: C0046: Identifier 'GVL_Io_17160064_c083_41f8_9e53_208be7537753_HPS_7' not defined Compile complete -- 3 errors, 0 warnings I attach the project. What am I doing wrong? Thanks!

I think you can use the newer versions. For a explanation from CODESYS, please read this post: https://www.codesys.com/the-system/versions-modularization.html

Hi, I'm using SP19 Patch 5, the software is also updated from SP18 Patch 5, I forgot to mention this. I will try a newer patch to see if it fixes the issue. Thanks for your help.

Thank you for your answer. Finally I don't confirm that it used to work before. It seems that the IO-link Package is needed is you want to configure the network, but you don't need it if you use generic IO-link devices.

yes sure. Thx for your support! This is the Codesys project stripped down only to my EtherCat and OneWire Configuration. The Project now contains only one OneWire Master on GPIO4.

Post by timvh on Access Violation sherd memory ^{CODESYS Forge talk (Post)}
Maybe it is better to use Interfaces to access the objects instead of pointers. But besides that, is "read_obj_ptr" a method? If yes, you need to call it, so add brackets behind the method call: read_obj_ptr();

Hi, how do you change the Git local repository folder name? It is called "project" by default, so we would like to rename it to something more descriptive especially for the remote repo's sake. Thanks!

Did you check the communication with a sniffer ? (ex. Wireshark) to check if the holding get to zero by a wrong writing (client initialization?) o something else?

Post by lzml on HTML5 visualization controls disabled on CODESYS Control for Linux SL - overlay not supported? ^{CODESYS Forge talk (Post)}
Thanks for the suggestion - I updated everything via the CODESYS Installer and restarted, but I'm still hitting the same error. What I did - Updated via Tools > CODESYS Installer - Visualization system libraries (VisuElems, VisuElemsAlarm, VisuInputs, VisuNativeControl, etc.): 4.7.0.0 -> 4.10.0.0 - CODESYS Control for Linux SL: 4.15.0.0 -> 4.21.0.0 (based on CODESYS SDK 3.5.22.20) - Restarted CODESYS Development System Checked project environment (Project > Project Environment) after restart - Compiler version: 3.5.22.0 - Library versions: all up to date - Visualization Profile: CODESYS Visualization 4.10.0.0 - SoftMotion version: 4.20.2.0 Result: compiling with Device = CODESYS Control for Linux SL still fails with the same error: "Overlay is not supported for your target visualization device." The custom HTML5 control is still disabled/missing from the Toolbox with this Device selected (same as before), and still appears normally when I switch the Device to a Windows target. Is there anything else specific I should check (e.g. a setting on the Device description itself, a different SL package/edition, or is WebVisu overlay for custom HTML5 controls simply not implemented yet for CODESYS Control for Linux SL regardless of package version)? Any pointer appreciated.
