Does latest Tow-Boot install/work correctly for everyone?

[tophneal]

After a few years of rocking a BSP img on my emmc (for that sweet S3) and not booting into it, I'd like to switch fully to a modern install of Fedora since I've been booting a pre EFI Fedora img from SD as my unofficial main boot.

Since Tow-Boot is needed for a modern Fedora install, I went and grabbed the latest version (2022.07-006) from Github. After writing spi.installer.img to several different and known working SDs, as well as using dd, nandwrite, and flashcp to write it directly to /dev/mtd0 (all indicated successful writes in terminal) I cannot get my PBP to boot into the installer menu, or show anything tow boot related at boot up when writing directly to the SPI. (At most, I get a solid-lit green power LED and a black screen when booting the SPI installer SD.)

I've also tried going back a few versions, including 2021.10-005 and 2021.10-03 (which I recall successfully booting and installing a year+ ago) and I get the same results from them too.

So I'm curious now if anyone else has had this or a similar issue when trying to install tow-boot through SD installer or writing directly to mtd0 from within a booted OS. I'd raise it as an issue on the Github, but I want to be sure I haven't overlooked any potential solutions and I know @samueldr has indicated he isn't able to be as active in maintaining/troubleshooting as before.

EDIT: it was pointed out, I should add the commands I've run to write the installer to SD, and the .bin to SPI. Please note, the SD card is read as sda by the system. 


dd (as per the tow-boot pbp page:

Code:

sudo dd if=spi.installer.img of=/dev/sda bs=1M oflag=direct,sync status=progress

nandwrite:

Code:

sudo nandwrite -p /dev/mtd0 Tow-Boot.spi.bin

flashcp:

Code:

sudo flashcp Tow-Boot.spi.bin /dev/mtd0

I ran 

Code:

sudo flash_erase /dev/mtd0 0 0

between each nandwrite or flashcp.
