Is there anything we can try/do/report on to help the developers towards a patch for V2.7?

Links to a patch for the F20 v2.7 firmware (and a pre-patched image) are now on the ErosQ wiki page.

Thank you! Thank you! Thank you! Flashed my F20 using the pre-patched V2.7 image. Works great! Line out is working.

I also have an F20 that came with FW v2.7, and have been running the native port thanks to @amachronic 's efforts in https://forums.rockbox.org/index.php/topic,54228.30.html.

Thanks, @azndante, for posting your results!

I was surprised to hear you have got the line out working, so I followed in your tracks. I restored the native bootloader from the backup I made with amachronic's bootloader (I used v6) in the thread linked to above. I then updated as you, @azndante, with the pre-patched image from https://www.rockbox.org/wiki/AIGOErosQK. And indeed, this got the Line Out on my unit to work under Rockbox.

Let's hope the same will be possible with the native port in the future!

Thanks!

In the interests of us trying to deduce what has changed hardware-wise for the the line out without actually buying a new device myself, could someone who has used the native port on one of the newer devices describe what happens when you try to use the line out port in detail? I'm mostly interested if there are any signs of life from the line-out port:

Does the behavior change at all when you have both headphones and line-out plugged in?

If both line-out and headphones are plugged in and you unplug one of them, is there any popping in the other output?

Is there any popping from the line out when turning the player on/off?

We may have to just play with some of the GPIO lines that control the audio hardware (assuming they haven't been moved) and see what's changed. My money is on a change with the stereo switch, personally.

I have not used the native port. I can quickly downgrade to V2.5 using the hosted port and perform the testing you mentioned. Will that be the same?

Unfortunately I don't think so, or at least it would add another layer of confusion to trying to figure anything out. We'll just have to keep waiting for someone to test it out. Thanks for the offer though!

Just ordered a Hiwi Walkmen from Amazon, it came with 1.5 firmware. It rejects a patched 1.3 fw. Too sad to run this device on vanilla fw

EDIT: Actually, manufacturer gave me the 1.5 fw image. Does it mean I am good to install a native port?

Well try to patch it with Rockbox Utility. See instructions: https://www.rockbox.org/wiki/AIGOErosQK#Installation

You should also share firmware so Rockbox devs might prepare and publish pre-patched image.

[amachronic]

Patching the firmware is for the hosted port, and unless the v1.5 firmware is byte-identical to one of the existing images, the patches on the wiki won't work, nor will Rockbox Utility be able to patch the firmware. You would have to share the v1.5 firmware for a patch to be created.

To install the native port, you don't need to patch any firmware. Use these instructions: https://www.rockbox.org/wiki/JztoolInstall

That what wanted to do - what is the best way to share? The wiki doesn't accept registrations anymore.

Upload it to a filesharing site (eg. dropbox, google drive) and post a link here.

Here is the 1.5 firmware for HiFi Walker H2: https://drive.google.com/file/d/1oZxpT8HNgsMVfM0MXmQnTxTTLzTXpixk/view?usp=sharing

Okay, here is a patched version of the H2 v1.5 firmware:

   https://www.shaftnet.org/~pizza/rb-H2-v15.upt

Rename it to update.upt and put it on the sd card root, then see if you can update the firmware successfully.

If it works, I'll add this (and the binary patch) to the wiki.

Thanks, I was able to update the device using provided fw, and run the Rockbox!

Pre-patched H2 v1.5 firmware and a binary diff added to the wiki.
