I have a 16GB micro SD card, on which raspbian strecth 2018-03-13 is installed (via win32diskimager, earlier formatted via SD card formatter). It works perfectly for my RPi zero model, but doesn't work for my RPi3A+ model. Though my RPI3A+ works perfectly for 2020-05-27 version of raspbian, but because that version doesn't support linux tool "perf", I am willing to use the older vesion which supports "perf".

How am I supposed to access the older version of raspbian stretch on my RPi3A+ model? Or is there any way where the perf tool can be accessed / installed for the latest version (2020-05-27)?

The Pi3A was released on 15 Nov 2018.

Any OS older than this won't work, although you COULD try updating kernel and firmware from a later release.

NOTE DO NOT use rpi-update (at least without selecting a Stretch compatible release - which is not quite straightforward).

Running sudo apt-get update; sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel will install the latest supported kernel/bootcode, but this assumes you have a Pi that can boot - should be OK if run on the Pi Zero.

  • I inserted the SD card into RPi zero and ran the above 2 mentioned commands: sudo apt-get update; sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel . After that, I inserted back the card into my RPi 3A+, this time the green light did blink thankfully, but still I couldn't connect it to my laptop. What could be the possiblereason for that?
