JTAG / Re: ARM-USB-OCD-H small amplitude of the TTCK and other signals

Yes, this is half of the information. For ARM-USB-OCD and ARM-USB-OCD-H, VREF is also used to adjust the levels of all JTAG signals near the targets voltage.

JTAG / Re: ARM-USB-OCD-H small amplitude of the TTCK and other signals

Thank you, problem was fixed!

ARM-USB-OCD-H, ARM-USB-OCD User`s Manual have only information: Pins 1 and 2 of the JTAG connector are voltage reference that probes if the target is already
powered by another source. If it is not, the ARM-USB-OCD would attempt to power it by 5V at pin
19 of the connector.


And no information about output stage to understand how it work.

iMX233 / Re: Tv Output from IMx233
« Last post by LubOlimex on December 10, 2018, 02:54:30 PM »
Always first test with the official image that we recommend. The official Arch Linux image that with tested video output can be download via this torrent here: https://www.olimex.com/wiki/images/6/6d/Imx233_kernel_2.6_ARCH_FS_WIFI_release_5.torrent – user name/password = root/root.

If there are problems with the video output using the above image, then the problem is probably in the converter.

Do you have USB-serial adapter attached to the board’s U_DEBUG pins? Does the board boot successfully using the official image linked above?

iMX233 / Tv Output from IMx233
« Last post by akhil on December 10, 2018, 09:24:14 AM »
Hello,

            Can anyone please share a working link of the os that can be loaded to the Imx233 and alongwith the TV output support. I saw some links to get the Archlinux and i tried to download it to the chip but it is not helping.
Any help is greatly appreciated.

Thank you,
Akhil

Did you try the Arduino examples that we provide:

ESP32 / Re: ESP32 Gateway Setup

What? "Passing the Ethernet data to the RJ45" - ESP32-GATEWAY has only Ethernet port with RJ45 connector. Maybe you meant WIFI data to the Ethernet's RJ45?

ESP32 / Re: ESP32-POE power options

The reset that you mention is not related to the power sources. If there is failure when there are two power sources applied ESP32-PoE will NOT reset but either your ESP32-PoE, your USB-ISO, or your computer would get damaged.

JTAG / Re: ARM-USB-OCD-H small amplitude of the TTCK and other signals

What is the voltage of the target? I feel like you would need to connect pin #1 VREF to the target's supply, else JTAG signals would be at 3.3V per default and you might experience problems with signal's levels. Especially if the target's voltage is lower than 2.0V.

I think you are missing some submodules of the axp driver. Don't know the names ATM, however.

Are you asking why does the Arduino code do that?

If so, this forum may not be the best place to ask as I suspect no-one here wrote the code.
