IQ POCKETBOOK UART Conect

[Michal Jancik]

Hello everyone !!

For those even for less experienced users who are looking for a procedure on how to connect and use UART on Pocketbook readers, I would like to share my following procedure, which you will find:

Interesting. Do you have a project in mind now you have a UART connection?

Interesting trick with the connection and the clamp. I soldered mine to stay on the connected side.

Hi.
I had to use the clip because I often had a problem getting into the console, I had to disconnect and reconnect (on the fly) in order to type commands (to appear after pressing ENTER #,it didn't even help when I sent ^C through the terminal)

..as always, everything has its pros and cons
However, there are also disadvantages to using a clamp, such as the other side of the clamp touching the screen.
Also, you can't move the electronic reader too much so that the terminal doesn't move outside the UART pins on the motherboard. .

PS : Unfortunately, I don't have any projects or ideas, I don't even have time, as unfortunately it often happens in the life of a mere mortal

nhedgehog... do you do anything cool with the UART/RS-232 connection to the pocketbook?

[nhedgehog]

Sorry no, just keep it in mind in case I brick it (again), sic.
But I do like to read with it!

Can you force-flash the FW over serial?

[nhedgehog]

Didn't try it. I did not have a deeper look into it and wouldn't do it as long as I don't have a way to safely backup and flash the board.

I would also be interested in that.
I know that it is possible to start an update with a swupdate command (for updating from the swupdate.bin file, which must be in the root directory), but in this case it is not a re-flash but an update.

I am interested in Re-Flash because I have a broken pocketbook that I need to reflash.
After powering on, an error is displayed:epdc_default_init ERROR cannot open eink

When holding down [ESC] key at start-up you can also get into UBOOT, but for now I didn't have time to look up how to re-flash the unity..

Nice fix One could also consider adapting an IC clamping tool (for BIOS), provided its prongs/beaks/... reach that far.

Is the USB FEL mode an option?
