 displays aren't packet-aware or know about the chip's command set or such.
 This is really only useful for debugging systems-level issues withing
 the device or blisp itself.
+
+## Troubleshooting
+
+### macOS
+
+Depending on your current system security settings, modern versions of macOS requires all software to be notarised before you are able to execute it. This is specially true for software that is downloaded directly from the internet.
+
+If that is the case, you will get an error that looks like the following:
+> **“blisp” cannot be opened because the developer cannot be verified.**
+>
+> macOS cannot verify that this app is free from malware.
+
+In that case, you will need to remove the *quarantine* flag that macOS adds to the executable. After that you should be able to run **blisp** as normal.
+
+```bash
+xattr -d com.apple.quarantine blisp

Dom Rodriguez	d51e7bcc1e	fix: Fix mismatching format strings when writing We were using the incorrect format string - this commit fixes that. Signed-off-by: Dom Rodriguez <shymega@shymega.org.uk>	2024-12-02 09:27:13 +01:00
Dom Rodriguez	d63612c256	fix: Make blisp check for existing file before flashing This commit adds a simple check to both blisp commands that checks the passed firmware .bin file exists, and is readable. Justification: I flashed my Pinecil V2 that arrived today, and misspelled the filename. blisp erased flash, and then exited - it did not check the firmware .bin was readable/accessible, which meant my Pinecil was soft-bricked. I have tested the change, and it works for both commands when the input file isn't readable. I had to declare the `cmd_{iot,write}_args_print_glossary` function as static before the call, so that we don't use undeclared functions before we call them.

Terence Noone	5634b678f3	Fix linking with argtable3 CMake interpreted `argtable3` to mean add `-largtable3` rather than to use the imported argtable3 target. This worked when using the bundled library, but broke with native libraries.	2024-03-03 00:46:22 -05:00
Terence Noone	8dbb58353b	Do not build for both arm64 and x86_84 on macOS. While this might work when using bundled libraries, this breaks with system libraries as they are all compiled for arm64.
