AGPTEK Rocker
ZiberPax:
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

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.

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.
