AGPTEK Rocker

[elakir]

As of reported charge, voltage of the battery is reported by underlying OS (linux). It does not report SOC (state of charge). The mapping of voltage<->percentage of charge available is totally uncalibrated and assumed linear from 3.4 to 4.2V which simply is not true for li-ion. If someone run battery_bench plugin and provide results I can correct this.

Hey. The same problem as in the photo. The folder ".rockbox" is put in the root of the SD card and there is "update", but nothing works :c

Hi, is this the first time installing rockbox on your device? If so, did you follow this:

"Instructions for install:

Extract the folder out of rockbox.zip Take the folder out of that named ".rockbox" and put it directly into your sd card. Put update_rb.upt directly into sd card as well, and once in there, rename it too update.upt

Next you'll need to choose the update firmware option in agptek rocker settings. It should upgrade and then you'll have a choice to choose rockbox, the original agptek rocker os and some tools"

What files did you download for the update or did you compile them yourself?

I suspect you are hit by known bug that performing update (with update.upt) removes mountpoint for SD card. Try to boot original firmware once. It should recreate necessary directories and rockbox should be able to start on subsequent boot.

Ok. Got two benches (thanks!) which looks pretty similar. I'll tweak calibration curve soon.

I tried to do the same with the original firmware, as advised vodz. But it did not help. First I install Shenzhen Benjie BJ-T6 V1.04Beta Firmware. After I put it in the root folder of the .rockbox and uptate (I formatted my SD, so I have nothing there). The same mistake. The first file is the original firmware, the remaining 2 that I put in the root

1) put modified update.upt in the root of SD
2) put .rockbox folder in the root of SD
3) Boot *hiby player*
4) Shutdown player
5) This time it should be possible to boot rockbox

Hi guys,

I am also thinking on getting a Benjie T6 now that there is Rockbox support (the battery of my old Clip Zip is giving up).

Those reports on battery duration are a bit worrisome, but it wasn't clear to me if you are testing using bluetooth or if you are using wired headphones. I expect the duration using bluetooth much less and I am interested in how long it last using just wired headphones.
I guess that duration also depends on what file you are playing as some audio formats might be heavier in CPU and memory card reading. If i remember correctly the Sansa Clip Zip has a 290mAh battery, and the Benjie T6/Rocker has a 600 mAh, so it is disappointing to know that it last less than the clip zip with double battery size!

One more doubt: do you know if the Benjie T6 has the exact same battery than the Rocker (same manufacturer)?

Thank you in advance

It seems that the biggest power hog on this thing is the class AB amplifier vs class D of (Sansa clip).
https://statics.cirrus.com/pubs/proDatasheet/CS42L51_F2.pdf page 75 suggest something like 150mW which is (3.7(volts) * 0.6(Ah) * 0.7(losses)) / (0.05(cpu watts) + 0.15(amplifier watts)) = 7.7 hours .
I am  wondering if that noise on low volume that adjusting gain fixes is actually caused by microphone left open.

[tethyrian]

Yes, both are present but I haven't ever tested those actually

I talked to an anon today who helped me out by telling me about and testing all the features I needed(even ones he didn't understand and thanked me a lot for teaching him about!). I decided to buy a Rocker v2 and honestly cannot wait to try it out. I wanted to echo the comment above me and say thank you so so so much for bringing rockbox back to a modern player. I honestly thought for a while that dedicated audio players were of a bygone era and am so happy to have found this product and port.

I know a decent amount of C and C++, etc. I am definitely not very well versed in the linux kernel or hardware programming in general but if there is anyway (or where) I can contribute now that I'll have a device on hand, I would love to offer my time.

This is a treasure.

My sansa fuze died yesterday morning - probably failed battery.
Read this blog, ordered a Rocker V2.
Rocker arrived at 15:00 today.
Inserted SD card, it played files perfectly.
Downloaded Milardo files post #114
Followed instructions from his earlier post - (easy drag drop on mac of the .rockbox folder in the zip.)
The update took less than 10 minutes from download to install.
Rebooted into OS player first then reboot into Rockbox.

16:00 I have a new player fully Rockboxed.

version b9467e9347-180409
firmware 1.2 on the Rocker

bonus - a standard USB charge port, no sansa proprietary cable needed!

kudos to wodz for the port and Milardo for the simple install.

[wodz]

Just to get you informed - Agptek Rocker port got merged upstream. I didn't make tests after merging and build script still points to my github branch but I'll sort this out soon.

WOOO HOOOOO!!!!!

I've been using it a lot these past few weeks.  Great port.  Thanks so much.

Hi Everyone,

I want to puchase the Agptek Rocker from amazon and install rockbox on it.

Does rockbox support bluetooth?

I understand that it is now in the main build is everyhting working fine with rockbox?

To install rockbox I should follow these steps right :

1) put modified update.upt in the root of SD
2) put .rockbox folder in the root of SD
3) Boot *hiby player*
4) Shutdown player

Then to upgrade rockbox I just need to download the latest rockbox build and replace the .rockbox folder?

Once I have my Rocker, I will be able to help you for the devellopment.

Do you think ot will be possible to add it to the officiale rockbox installer?

Best regards,

N3ST

My second Clip+ just fried its flash, so I picked up a Benjie T6 to replace it.  All in all, it's looking pretty awesome.

Running the latest git code (20bdfa82) and there are some issues.  My question is where I should report them -- in the forums (this thread?), In the flyspray tracker (no AGPTek Rocker entry there yet), the main mailing list, or where?

 * Wonky keymaps in some places
 * volume control steps are very gradual
 * LCD doesn't seem to update when skipping or seeking tracks, but does when pausing/playing.
 * Need to expose output gain selection (to select between HP and Line out)

Thanks!

No. It is possible but not implemented yet.

Yes, that is correct procedure.

Sure it is. Its just someone has to do the work. My free time very limited unfortunately.
