Issues installing safe shutdown scripts for Nespi4 case

[RetrOkada]

Hi everyone,

Recently I got the Nespi4 case from RetroFlag, and have installed my Pi 4 Model B into it.

The issue I'm experiencing is that I can't seem to download the "Safe Shutdown" script.

I followed the instructions from https://github.com/RetroFlag/retroflag-picase.

I pressed F4, followed by Alt-F2, to go into the Terminal. I entered "root" and "recalboxroot" to login. I then entered the following command:

wget -o - "https://raw.githubusercontent.com/RetroFlag/retroflag-picase/master/recalbox_install.sh" | bash

Upon pressing Enter, I receive the output as shown in the image above. I hope it's clear enough; I attempted to photograph my monitor.

Without the scripts, there is a red LED on the front of the case, and the power and reset buttons do seem to work. However, as I understand it, without the scripts, the buttons don't shut the system down cleanly.

The switch inside the case is set correctly.

I am using a fresh install of Recalbox, version 7.2.1.

Does anyone have any suggestions as to what I could try?

Many thanks for any help.

Sorry for the issues with the image, and the blank post. I am using a screen-reader due to a visual impairment, and it struggles with some of the page elements.

Is the image shown here?

Hopefully it is showing now. Again, sorry for the issues.

@retrokada Hello,
with the help of users, we found the origin of the nespi4case problem. I'll write a little tutorial this week end to install the 7.2.1 version using a nespi4case, with or without a HD/SSD connected.

Oh okay brilliant️. Any chance you'd be able to reply here once you've written it?

Again, really appreciate the assistance.

So, I was able to fix the issue, and the script is now working perfectly. Below, I will outline the steps I needed to take in the hope that it will prove helpful to anyone else who may be experiencing similar issues.

Firstly, it's worth double-checking the "Safe Shutdown" switch inside the case. In my previous post, I stated that it was set correctly; it wasn't. Turns out that I routed my cables poorly during my first assembly attempt, and this repositioned the switch, so definitely double-check that. There is, apparently, a really helpful diagram in the manual. However, for people like me who are unable to read it, there is an easy enough way to verify that the switch is set correctly. Set the case in front of you, with the SSD compartment and USB ports at the front, and the power, Ethernet etc ports at the back. Then ensure that the "Safe Shutdown" switch is positioned towards you. After I fixed my mistake, the script installed properly.

However, I then ran into another issue. The buttons on the front did invoke the script. Problem is that the system would crash before properly shutting down. The only way to break out was to pull the power cord. Luckily, a solution is offered in this Github issue:
https://github.com/RetroFlag/retroflag-picase/issues/101

Essentially, it's necessary to ensure that you have the correct firmware installed for the top case/SSD bay, Otherwise the script won't run correctly. There are separate firmware versions for booting from a Micro SD card and booting from an SSD. You need to use the firmware which matches your boot configuration. For example, if you're booting from a Micro SD card, it's necessary to ensure that the matching firmware is installed.

It seems that the process can only be carried out on a Windows machine; for me, a Windows VM was sufficient. You'll also need to first disconnect the top case from the Nespi4, and connect it to your computer.

The firmware can be downloaded from the following page. Just scroll down and select "Firmware Download":
http://www.retroflag.com/nespi-4-case.html

You'll end up with a zip file, which will need to be extracted. You'll then have a folder called "How_to_boot_from_SSD". Open this, followed by "Method 2 update firmware". Run the "FwUpdateTool_v1_19_16_24.exe" file, doesn't require installation. In the update tool, click the "Load File" button, and browse to the "Firmware" folder in the aforementioned directory.

This is the crucial bit, as you need to select the correct firmware according to your boot preference. If you want to boot from a Micro SD card, choose "JMS578_STD_v00.02.01.04_UAS.bin". If you want to boot from an SSD, choose "JMS578_STD_v00.02.00.09_NO_UAS.bin". Then click "Run", and wait a few seconds for the firmware to install. Click "OK", and safely remove the top case from the computer.

After connecting everything back together, the script should run without any problems. Just to be safe, I started with a fresh installation of Recalbox, and installed the script.

Of course, all of this may be thoroughly detailed in the manual; I wouldn't know.

Anyway, I hope that this is helpful to someone.

Cheers️.
