@valentt,

Sorry, I hadn't realized there was an email address I could send the Hame A5 file to.  Sent now.  There's not much in my build except support for usb/serial.

Thanks! I'll try it out soon.

Re Hame A5

I flashed a second one yesterday with the file I sent to valentt.  I didn't solder on serial, I just used spring test clips (Mini Grabber Test Probes) on the serial pads--Left is TX, Middle is RX, Right is 0V (rightmost three pads (of 4) with the pads to the bottom right).

As with some other of these Ralink devices (Poray M3, for example), the A5 doesn't boot with the serial connected.  Disconnect it and it boots fine and can be accessed with telnet through the ethernet cable at 192.168.1.1 as usual.

Maybe, it is because of the noise on the serial cable, oscillator can't start up. For me, I test the Hame MPR A1 with PL2303 and FTDI serial cable. The pl2303 can't communicate with MPR-A1, but the FTDI chip works fine.

CH341 also works fine

it is enough to add Squonk42 patch to compile firmware for Hame A5  or i need to do something more.
please send your firmware to me too. and if possible image of the PCB where are TX,  RX,  0V  are marked.

pl2303 usb/serial worked for me for gaining access to flash, but the Hame A5 would not boot to openWrt with the serial connected.  It booted fine without it (after flashing).

My build had the kernel command line modification for 16M--otherwise Squonk's three patches as of early February.  I don't know what patches would be required with trunk at present.

Valentt said he wanted to put my build file on his dropbox account.  My build may be of limited utility, since it has almost nothing enabled except usb serial.  There appears not to be enough ram for sysupgrade to run, so any reflashing for additional features would need serial console anyway.

as i understand, i need to apply Squonk's patch and make kernel command line modification for 16M.
how to make kernel command line modification for 16M?

@derrij just try this way.

 make kernel_menuconfig 

find kernel hacking , enter and then find(rootfstype=squashfs,jffs2) Default kernel command string
enter again and manually set SDRAM value rootfstype=squashfs,jffs2 mem=16M

no.  there is no need. Its a proper Mod.

@p1vo

Thanks , finally my Hame got LuCI after all.

@p1vo,

I've sent you a PM regarding your postings - if you're reading, can you reply?  Thanks!

Re: Hame A2

Hi
Here is my patch to compile OpenWrt new trunk (with Device Tree) for Hame MPR-A2 router:

https://github.com/shmygov/OpenWrt-HAME-MPR-A2

It is based on the Squonk's patches.
(Hame A2 is same as A1, but with 8MB flash, 32MB RAM, and 5200 mAh battery.)

It is working OK on my A2 which is a genuine Hame from the manufacturer (not a clone).
However, there are still some problems with WiFi driver: low data rates, unstable operation if the AP is used without wifi password set.

Hello all,

I would like to try (my 1st time) to perform a ram upgrade - will the type of ram
used for wr703n upgrades be compatible with Hame MPR-A1 ?

Thanks in advance,
Marek

You need a 256Mbit (32MB) SDRAM (not DDR) chip in a 54 pin TSSOP package.  The device can also take 64MB chips, but only 32MB will be used.

The cheapest place to get this memory is from old laptop memory cards.  Search for 256MB PC133 SODIMM on ebay, and find one that uses 8 leaded chips.  Next, check to make sure the seller is not using a "stock image" so you are really getting a module with 8x leaded chips.  Any question, just ask them.  A lot of sellers are using incorrect images but will admit it.

I bought my (64MB) chips on a 512MB PC133 SODIMM from mem-store on ebay for $15.  I used a heat gun to heat up the module.  The chips just fell right off and were ready to solder on with no cleanup.

When removing the old DRAM from the board, I highly recommend Chipquik.  It's not cheap, but using a heat gun on the HAME has a great risk of melting the switches and dislodging the tiny components.  I removed the old IC with chipquik, then cleaned the pads with solder wick and soldered a new chip on. 

With a little flux, it's easy to solder the tiny leads without bridging them.  Line up the chip in it's proper position and hold it with your finger.  Solder one corner pin.  Double check alignment while you can still move it around, then solder the opposite corner and continue to solder all pins.

Good luck.

wr703n uses TSOP 66 package

the 2 ram on lower right are both TSOP 54 pak (micron 32MB and ESMT 16MB), used to upgrade my HLK module.

thanks to gaplee, for his work and help.
now my hlk module runs hame openwrt with luci.

@oschemes,
thanks for the tip about chipquik, the video looks really simple to use.
i used hot air to pull out TSOP 66 and TSOP 54. it almost damage the pads.
i'll surely try chipquik.

@n1x0nuk
i still dont know where to buy TSOP 66 ram.
if you find one, pls. tell us.
i like to try to upgrade my wr702.

@elaber
Congratulations. Nice work, and nice picture.
My hlk-rm04 module select the external antenna by default, i do not realize that for a long time,  and find it until not long ago. How about yours, do you notice that.

Power of RT5350 is unpowered, only 100mW. WR703N is about 500mW.

@oschemes - thanks a lot for a detailed description, much appreciated.
I must admit I already melted the battery indicator switch while trying
to unsolder the memory Ordered PC133 256 (32MB modules) for hame mpr-1 upgrade.

@elaber - While I know it's not a best deal in the world, there are offers on ebay
that sell 1x64MB ram chip + 8MB flash for ~$10 , not ideal but I've just ordered one
as I can't find any matching memory for 703n (fingers crossed for using raspberrypi
as STI flash programmer)

regards,
Marek

I would like to use my Samsung (xcover) like 3g modem and connect it to the HAME. Is that possible?

With stock firmware I've got this
# lsusb
0000:0000 (bus 2, device 1)
04e8:684e (bus 1, device 2)
0000:0000 (bus 1, device 1)

but admin panel tells me there is no 3g module.

Tnx for any hints.

Driver for switch with features: led polarity control (via swconfig or from DTS directive ralink,led-polarity in esw section), bc-storm protect and transmit good/bad packet counter. I will try to add QoS and IGMP forward. Link

is mine hame a5 only 8Mb of  RAM?
boot log http://pastebin.com/sY0x5GUf
no way openwrt install on my A5?

@derrij--Hame A5 works with openWrt after patches are applied and kernel command line modified for 16M
(The following is from someone's post earlier in this thread)

kernel command line modification for 16M:
make menuconfig to set ralink architecture
add "mem=16M" command-line option for the kernel to see all 16Mb since the bootloader tells it there's only 8Mb.

To do so you need to do "make kernel_menuconfig" in the OpenWRT dir, enter "Kernel hacking" and add "mem=16M" into "Default kernel command string". Then do make.

how to flash A5?
how to interrupt the booting to get a U-Boot-console. tpl or how?

Many thx shmygo ! Your patch works great also on A5 !

I've replaced the RAM with 32MByte, shortened a missing resistor near to the left bottom edge of the rt5350 and changed in the dts file the flash type accordingly getting:

setenv bootfile openwrt-ramips-rt305x-mpr-a2-squashfs-sysupgrade.bin
tftpboot
erase linux
cp.linux

Only one thing left - I get lots of following message

root@Hame-A5:/# logread | tail -2

Does anybody know how to get rid off this ?

@derrij--I have two Hame A5s flashed with openWrt--trunk, self-compiled to get the patches included. 

You enter the flash command from serial, and the image is downloaded via lan cable.  For the first one, I soldered on the serial connections.  For the second, I used mini grabber test hooks:  http://www.ebay.ca/itm/Random-10-Single … 1e7a37b1e3

For the serial connection, I used a pl2303 usb/serial dongle from a Windows 7 PC, with putty.  I'm using tftpd64 for my tftp server.

On the A5 board, with the 4 pads down and to the right, rightmost is 0V, next is RX (to tx on my pl2303 adaptor), third is TX.
