Pogoplug E02 problems with u-boot
October 16, 2014 02:57PM
pogoplug e02
I am unable to see anything through putty, my USB to TTL Converter is http://www.ebay.com/itm/New-1PCS-5PIN-PL2303-USB-To-TTL-Auto-Converter-Adapter-Module-unit-For-arduino-/141150349286

I am following this guide:
http://blog.qnology.com/2013/10/pogoplug-e02-v2-serial-connection.html
Tested on 2 compters, winxp/win7 x32.
Putty window just stays blank.


If i connect sata drive inside 2.5" usb 2.0 external case it boots fine into debian installed on hdd, rescue system http://forum.doozan.com/read.php?4,7915 works too.


Here is fw_printenv output:

Is this the latest completed set of U-Boot envs ?
http://forum.doozan.com/read.php?3,16148,16148#msg-16148

I can edit my env with "setenv" within uboot serial console and the save it.

Yes, you can set the envs manually one by one using envs in that post, or use the attached script in this post to set the default set of envs:

- Put this script on your rootfs USB /boot directory: 
/boot/uboot.2014.07-tld-1.environment.scr
- Interrupt serial console
- Execute command: 
> usb start
> ext2load usb 0:1 0x800000 /boot/uboot.2014.07-tld-1.environment.scr
> source 0x800000
- Adjust the other envs following the instruction in section B.
- boot

Typed each env into uboot env &removed mmc parts, so now my printenv is much more clean (all outputs are from nc)

Because your bootcmd does not have rescue boot option. Put it on boocmd like this so if no disk drive, then it will boot into rescue system: 
bootcmd=run bootcmd_usb; run bootcmd_sata; run bootcmd_rescue; reset

It's where the envs are located (total of 1 block).

Than for your responses.
Now rescue is working & booting from usb.


+ i finaly managed to restore to life my USB to TTL Converter:
http://blog.qnology.com/2013/10/pogoplug-e02-v2-serial-connection.html

my initial connection was:
gnd -> gnd
txd -> txd
rxd -> rxd

But when you look picture carefully you see txd is connected with rxd (and rxd to txd).

FYI, in case others coming across this while looking to solve serial connection problem.

In my observation, the serial module type PL2303 pinout is a "true" pinout so so we always have to cross TXD and RXD lines when connecting to the plug. RXD-TXD, TXD-RXD.

otoh, the serial module type CP2102 pinout is already crossed (i.e. the marker actually tell you what line on the plug to connect to). So they should be connected RXD-RXD, TXD-TXD.

YMMV.

I did mention the following and have it in nice bold black in the picture :)

Make sure GND on the Pogoplug is connected to GND on the USB to TTL converter.
TXD on the Pogoplug should connect to RXD on the USB to TTL converter.
RXD on the Pogoplug should connect to TXD on the USB to TTL converter.
