Reset was successful, and now I can start from scratch. Thanks for informing me on the alternative method.

@Chris-Stratton oh thanks, i'm newbie in that. i will try

@György-Farkas Thanks! I finally got it working with the FT231X. For some reason, I need to reboot my MAC every time I make a connection to the Omega 2.

UPDATE: I found that pulling the RST pin low (GND) causes a reset. Reading the RST pin shows 3.3vdc. This answers my question.

I'm relieved to read that most of us have difficulties to understand what is going on, on the onions memory (Memory Technology Device; MTD)*. OpenWRT is a router OS. So most of routers do not have a hard drive (block device)* in sens of a computer who stores data for ever. The firmware is a file where gets extracted in a ROM (Read only memory) = /dev/root mounted as /rom. Now in several layers** the omega-os (openWRT based) prepares the data to use ... How this could look like, I tried to explain already here on a simplified way (see also link to openWRT wiki [RESOLVED] UNDOO >> USB-Storage-as-Rootfs !! *What are the differences between flash devices and block drives? **If we have a look to the partitions now, we also can recognize what is used and produced in witch layer: root@Omega-24CF:/# fdisk -l Disk /dev/mtdblock0: 0 MB, 131072 bytes Disk /dev/mtdblock1: 1 MB, 1150464 bytes Disk /dev/mtdblock2: 15 MB, 15429632 bytes Disk /dev/mtdblock3: 7 MB, 7929856 bytes Disk /dev/mtdblock4: 0 MB, 65536 bytes Disk /dev/mtdblock5: 16 MB, 16580608 bytes For me everything is a bit learning by doing now. So I think to put this info's in to the wiki could help several persons. But before i do so, please correct if i see something wrong or to simplified

@Johan-Simons Yeah, we have a cron job called wifi-saint that runs every 5 minutes to detect if you are on configured to connect to a Wifi network but are unable to connect successfully. It will turn off the connection to the wifi network to enable AP in this case.

@Didier-Dorelien No problem! Please let me know if it works or if you have any other questions.
