Neo6502 / Trouble flashing firmware on N...

Last post by alicesphere - November 21, 2025, 10:36:44 AM

Hi everyone,
I'm new to the Olimex retro boards and just started working with the Neo6502. I'm trying to flash new firmware through the USB interface, but the upload fails halfway with a timeout almost every time.

I've followed the instructions from the Neo6502 resources page and tried different USB cables and ports, but no change. The board powers on normally and the bootloader seems to start, but the flashing process never completes.

Has anyone experienced unreliable USB flashing on the Neo6502? Is there a known issue with certain host OS versions? Should I be using a specific baud rate or tool version? Would flashing via SWD be more stable?

Any tips would be really appreciated. Thank you!

I mean, just look at the dts section I pasted.  The phy reset gpio is being set to gpio4 02, but the pinctrl for it is specifying gpio4 22. The node for the other ethernet is swapped as well.  The correct gpio is specified in the pinctrl, but the wrong one is specified for the reset.  They are each set to the others reset gpio.

Hi, I am using Linux a20-olinuxino 5.10.180-olimex #140708 SMP Fri Dec 22 14:08:29 UTC 2023 armv7l GNU/Linux on my A20-OLinuXino-MICRO REV. L but I can't find a way of adding support for the ILITEK 211706000 Touchscreen driver.

Can you please guide me on how to install the driver ?

Sorry can you elaborate further? I am not sure if I understand the problem clearly. They are GPIOs how can these be swapped?

There seems to be an issue with every dts patch I have found for this board, even the one in the olimex buildroot-imx repo. The ethernet reset GPIOs are swapped between the 2 interfaces.  For example, buildroot-imx/board/olimex/imx8mp/linux/0001-dts-add-imx8mp-olimex.patch:

Code Select Expand

&eqos {
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_eqos>;
    phy-mode = "rgmii-id";
    phy-handle = <&ethphy0>;
        phy-reset-gpios = <&gpio4 02 GPIO_ACTIVE_LOW>;
        .
        .
        .
pinctrl_eqos: eqosgrp {
        fsl,pins = <
            .
                        .
                        .
            MX8MP_IOMUXC_SAI2_RXC__GPIO4_IO22        0x19
        >;
    };

I was wondering why my yocto build only had 1 ethernet port come up, the patch I was using was messed up slightly different and managed to have the second ethernet configured close enough to work.

Last post by LubOlimex - November 19, 2025, 10:37:03 AM

Why didn't you just solder wires to the pads of the reset button. Just add wire at each side of the button and add a second button at the box...

Measure between the pads of R28 of continuality and see if there is connection.

Hello. Thanks for your response.

Really I wanted to export that button to my outer box, that will be a container for my A64. So I can turn it on and off.

Well, by now I just removed the 1K resistor R28 and pressing the on board pwr01 button, the shutdown behavior returns.

Please any advice on getting this functionality working, will be appreciated.

Thanks
