rosco_m68k - testing.
back to main rosco_m68k page.
2022-08-08: using my c1 FreeBSD workstation to test kermit transfers. again using a nanoUART. No dice, all transfers fail, even if
~/.kermrc is correctly set up
tingo@kg-core1:~ $ cat ~/.kermrc set carrier-watch off ; set flow xon/xoff ; robust ;
the machine is running FreeBSD 13.1-release
tingo@kg-core1:~ $ freebsd-version -ku 13.1-RELEASE 13.1-RELEASE
2022-07-05: tested with a nanoUART; on a Debian laptop, file transfers works without fail. On my FreeBSD workstation, larger file transfers might work but there are always errors. And small file transfers (example: ehbasic.bin) fails every time. Not sure why.
2022-07-05: testing - adding the following lines to
~/.kermrc makes kermit file transfers work
set flow xon/xoff ; robust
the complete file looks like this now
tingo@z30b:~$ more .kermrc set carrier-watch off ; set flow xon/xoff ; robust
(this is even in the documentation - sigh)
2022-06-12: testing - for kermit to work, this is needed
tingo@z30b:~$ cat ~/.kermrc set carrier-watch off
2022-06-08: testing - minicom also works on my FreeBSD workstation
tingo@kg-core2:~ $ minicom -D /dev/cuaU0 -c on -R utf-8
2022-06-01: testing - I got a new microSD card adapter today (DFRobot DFR0229), wired it up and tested -it booted straight from the card, like this

2022-05-26: testing - both mincom and screen works (once I found out the default speed is 115200, not 9600 as the documentation says). With minicom you have to set speed via the
menus, then start minicom like so:
minicom -D /dev/ttyUSB0 -c on -R utf-8. screen is just
screen /dev/ttyUSB0 115200, and then rosco_m68k prints this on console

2022-05-26: testing continues. I wired up a usb serial adapter and power to J1 (closed the jumper too). The usb serial adapter I used didn't provide enough power (voltage was only 3.4V after power up), only one LED was lit: picture. So I wired another usb serial adapter to the power input pins of the rosco_m68k instaed (remembered to open the jumper next to J1 too), looks much better now: picture 1, picture 2.
2022-05-26: with the build finished, it was time to test the rosco_m68k. First I measured with an ohm-meter that there was no short between +5V and ground.
