As I said I'm a newbie
Luckily I have an FTDI cable , but what software should I use as a
console to read data from PB? I have Windows 10.
Actually, when I plug PB to my PC it makes the sound of connecting and
a COM port appears in the Device Manager, but then another sound of
disconnecting. This thing repeats for 10 times and finnaly the COM
port disappears.
Thnx

If the LEDs are not blinking as expected, that does not sound
good. If you have a FTDI cable, you could try to connect it to
the PB as shown on the following page to see if you get any
messages related to the issue:

I'm assuming you are not seeing a COM port active for the PB on
your Windows PC, correct?

I have used "*AM3358 Debian 10.3 2020-04-06 4GB SD IoT*"
image file and I used "*rufus 3.1*" to flash the image.
As I said, all 4 leds lighted up sequencially and after a
while the user0 led flashed like a heartbeat and user1 led
kept flashing randomly.
That is normal as I have read, but still in my computer no
device was detected.
After some unplugging and plugging, I used "*Etcher*" to flash
the image.
Then I flashed some older images like "*Debian 9.9 2019-08-03
4GB SD IoT*" and "*AM3358 Debian 10.0 2019-07-07 4GB SD IoT*"
with "Etcher" too.
I have tried a different sd card but nothing changed.
Yesterday when I plugged Beagle in the usb port, an
"RNDIS...." message appeard but not any connection and only
user0 led stays constantly lit.
User0 led is about kernel, so is there any damage inside the chip?

What image did you flash to the uSD card?
What tool did you use to flash the image to the uSD card?

Hi, I'm a newbie with beagle board and I have a
problem with my pocket one.
I did all according to the quick start guide.
When i plugged it to my pc all 4 leds lighted up
sequentially but I was waiting for 1 minute and
nothing happened. There wasn't any new drive appearing
in my windows explorer.
Unplugged it without turning it off and plugged it
again. Same bahavior.
After a lot o sd card flashing and tries to boot,
things got worse.
Now when i plug the board only user0 led lights up and
stays open.
Have I damaged it ? How can I check if it has damage?
Can I fix it ?
Thanks
