For the past few month I have been unable to use my raspberry pi because of a HDMI problem. I have tried following this guide:https://howtoraspberrypi.com/raspberry-pi-hdmi-not-working/ Only to realise I have to enable SSH first. I then got out my microSD to SD card and put it in my Mac.

I then opened up terminal and did the following commands: cd /Volumes/boot and then touch ssh and was given the output touch: ssh: Read-only file system . I then read this article: Raspberry PI config.txt gets recreated and the custom modifications ignored

Does this mean that my microSD card is worn out or is something else wrong?

Additional Info

Computer Software: Mac OS X

micro SD card: NOOBS (Although I might have accidentally reformatted it and installed a new OS)

SD Card Partitions: boot and RECOVERY

Raspberry Pi Model: Raspberry Pi Model 3 B+

EDIT: I have also now changed config.txt by uncommenting #hdmi_force_hotplug=1 and #hdmi_drive=2 (This was done without SSH)

After reading a few more article I and checking my adaptor I realised that it was just that the switch (which until a few seconds ago I had no idea what it did) was causing the boot file to be read-only

EDIT: 1. This fixed the read only problem but as soon as I put the microSD in my RPI the SSH file was deleted.

  1. IN the end I ended up reformatting the SD and installing Raspbian Stretch and enable ssh via sudo raspi-config

  • You probably have other problems. The advice on creating a ssh file applies to Raspbian. NOOBS has a different partition structure and frankly is unsuitable for headless boot. The Raspbian boot parition is NOT the 1st partition on the SD Card.

  • @Milliways So what else would be needed to be done? I also changed #hdmi_force_hotplug=1 #hdmi_drive=2 and un-commented them without SSH. Is this a problem?

  • I am not sure that creating a ssh file would even work, but if it does it would need to be in the correct partition - include the output of diskutil list in your question.

  • @Milliways Using cd /Volumes/boot and touch ssh it created a Unix Executable.I also changed #hdmi_force_hotplug=1 #hdmi_drive=2 and un-commented them without SSH. Is this a problem? I have also now included the output of diskutil list in the question.

  • disk2s6 (which is the 2nd extended partition) looks like the Raspbian boot partition so you have edited the correct files. disk2s1 is the NOOBS boot partition. PS None of us use NOOBS (it wastes 1.3 GB of your SD Card) and it appears to have changed in how it labels partitions since I last tried.
