So this HAME MPR-A1 now works with OpenWrt? Any know issues?

No, WiFi working, Ethernet switch working, USB working, button working, LEDs working...

The only problem is the SDRAM capacity: only 16 MB sad

Any good place to order them? I fount them on DX for 24$ with free shipping, any better deals?

If you don't care for a clone, here is one MPR-L8 at 18.99 USD, free shipping, about 2 weeks for delivery (the one I have): works like a charm!

But the one above from @miguxbe may be a better deal if you prefer microSD + SD card and 32 MB SDRAM, and don't care about battery...

How about miguxbe's one - is that fully working with OpenWrt now? The card slots make it quite appealing smile

That what I suggested wink

But be careful, from what I can see from the top PCB picture, the microSD  SD is provided by a GL823 chip. Unfortunately, it looks like the microSD+SD is brought to the microUSB connector, but not routed internally. The only way around is to loop the microUSB connector to the USB connector, but you still have to provide power...

Ah - being a person of little electronics, I think I'd better stay away from this one. Thanks!

miguxbe--I see by your boot log that ttyS1 is initialized/found as well as the console serial, ttyS0.  Do you know if the pins for this are brought out somwhere?

serial8250: ttyS0 at I/O 0xb0000500 (irq = 37) is a 16550A
serial8250: ttyS1 at I/O 0xb0000c00 (irq = 12) is a 16550A

If you have an SD or micro-SD inserted, are they detected and made available?

Can you explain this a little more fully?

Does it look like GPIOs are available with this board?

No, just until the hardware guys have cleaned up the mess wink

Please refer to miguxbe's last picture: do you see the GL8823 chip right to the large SDRAM chip? And do you see its pins 18-19 routed around the large inductor "4R7", C190 and C1? These are USB D+/D- signals that are routed to the microUSB USB1 connector that is just outside of the picture.

This means that the microSD+SD are only routed to this microUSB connector, not internally, since the RT5350 only has a single USB interface.

This would provide microSD+SD to a PC when you attach the router, but the only way to benefit from them from the router itself is to loopback the microUSB and the USB connectors.

As for the GPIOs, I don't expect to have a lot available, but at least you have an easy to solder UART which is 3.3V LVTTL level, 32MB SDRAM and an unlike with AR9331, an USB host interface that is working wink

Squonk--Thanks for that explanation.  No wonder I was confused.  The enlarged "last picture" of miguxbe that you provided the link to for me doesn't come up, nor does linking to it from his original post by clicking to enlarge.  That's in Win7, and trying it with ie9, firefox, opera, chrome, and safari.

Does the sd wiring mean that even if you did connect the micro-usb and usb, you would have either usb or sd, but not both?

If you connected a hub to USB, could you then connect from the hub to micro-usb and have access to the sd?  (Sounds roundabout, and wouldn't give you much more than you could get with the hub itself--and of course, as you point out, you'd have to provide power.)

Yes , exactly
Yes, exactly!

Yes.

I've just compiled openwrt but generated file bricked mpr a1. Can anyone send .config of succesfull compile?

First, checkout a fresh trunk from subversion, then apply the patches and configuration as described in my previous post:
https://forum.openwrt.org/viewtopic.php … 41#p186841

Don't change anything else, it should work out of the box.

If not, post your bootlog, so we can tell what is going on.

I ll try again. ThankS

Ordered.

wink

Ordered a Poray M3 too. Maybe we should change the thread title to something like "RT5350 based routers" tongue

By the way, I still need to find out how the original firmware manages to switch between the cardreader chip and the external USB port on my HOTSION HOT-V9 (branded Poray PRP-X5).
Because as soon as you plug in an external device to the USB Port the cardreader is deactivated and USB seems to be routed to the external USB port.

no,   mach-dir-300-revb.c has include 620a1 LED and GPIO  define.

If using SPI for flash is really what you want you'll need to edit the kernel's boot parameters (either directly or in target/linux/ramips/image/Makefile) to use spi instead of phys.

If you have an SD or micro-SD inserted, are they detected and made available?

Ok, everything has been perfectly answered by @Squonk. Thanks @Squonk!! smile.
And yes, unfortunately the SD and microSD card readers works as a simple hub, I connected the microUSB to my pc and both readers work as a simple hub. I think that these card readers were thought to keep the router near a laptop, or something like that...

Finally, I think, that I or someone should create a new thread for the PORAY M3 or RT5350F devices, and not mix with the HAME beacause it could be confusing.

I think a wiki page for each device would be a good start. I've added mine some time ago and I'll add the Poray M3 when I get mine, if no one did it 'til then tongue

I flashed openwrt with hame's stock upgrade tool. without soldering and opening case. I think it is easy and needs nothing than an ethernet cable.

Is wif now working also?

Everything is working fine on my MPR-L8 (Hame MPT-L1 clone), but it requires patching and compiling the trunk, check my detailed post.

The only problem is the limited RAM capacity.
