Srec_cat - Multiple Values problem trying to insert CRC into binary file

 If you're facing issues with `srec_cat` when trying to insert CRC values into a binary file, it's important to ensure that you're using the tool correctly and that your input files and data are formatted properly. Here's a general process to insert a CRC value into a binary file using `srec_cat`:


1. **Create a File with CRC Value**: First, create a file containing the CRC value in the desired format. You can use a simple text file to store the CRC value.


2. **Generate a Checksum**: Use a tool or code to generate the CRC value for the binary data. Ensure that the CRC value is computed correctly according to the algorithm and parameters you need.


3. **Convert the Binary File to S-Record Format**: Use `srec_cat` to convert your binary file to the S-Record format. This step involves specifying input and output file names, ensuring that the binary data is properly formatted, and specifying the format for the output S-Record file.


   Example:

   ```sh

   srec_cat input.bin -binary -o output.srec -S19 -address-length=3

   ```


   In this example, `input.bin` is the binary file, `output.srec` is the output S-Record file, `-binary` specifies that the input file is in binary format, `-S19` specifies the S-Record format, and `-address-length=3` indicates that the address should be 3 bytes long.


4. **Append the CRC Value**: Use a text editor to open the S-Record file (`output.srec`) and append the CRC value from the file you created in step 1. The format of the appended line should match the S-Record format, and the address should correspond to the location in the binary file where you want to insert the CRC.


   Example:

   ```

   S3ADDRESSCRCVALUE

   ```


5. **Convert S-Record Back to Binary**: Use `srec_cat` again to convert the modified S-Record file back to a binary file.


   Example:

   ```sh

   srec_cat output.srec -o output_with_crc.bin -binary

   ```


   This command will produce the `output_with_crc.bin` file with the CRC value inserted.


Please make sure you have a clear understanding of the binary and S-Record formats, the CRC algorithm, and the specific requirements for your use case. Ensure that you double-check the formatting of your S-Record file, especially the CRC line, to match the expected format.


If you're still facing issues, providing more specific details or any error messages you encounter would be helpful in providing more targeted assistance.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
