Just a few technical notes on debugging the SSL Nucleus (mk1) through serial port. I will enventually update this article with additional commands tests.
First of all, you’ll need a USB to serial cable, which can easily be found on amazon, aliexpress and so on. Such a cable it about 1€, don’t spend more on it!
On macOS: open a Terminal and type:
screen /dev/tty.wchusbserial141330The actual name of the device may differ, but it’s probably be something close.
You now have a pretty nice shell, opened on your Nucleus, type “help” to show all available commands:
CMD>help
TP220_3 [] Daw channels layer 3 diags
ALLOC_3 [] DAW allocator
TP220_2 [] Daw channels layer 2 diags
ALLOC_2 [] DAW allocator
ACTIVE [] Ptoosl active send
TP220_1 [] Daw channels layer 1 diags
ALLOC_1 [] DAW allocator
TP180 [] Soft key diag
TP186 [] Layer Control
TP215 [] control groups
TP177 [] UDP midi
IP [] TCPIP Diags
ETHer [] PX1 Ether diags
DAW [] DAW config
CCC [] cc config
SOKS [] Soft key diag
FLIST [] function lists
TP234 [] Centre meters
TP199 [] USB KBD Functions
SVEN2 [] 7 seg diag
SURF [] ctrl surface diags
TP5 [] Control manager
TP86 [] Power up restore
LOG [] Logging
FRAM [] FRAM cmds
FS [] File system
RTC [] Real time clock
USB [] USB Kbd Diags
TH6 [] SPI Access
TH17 [] 675 Live Bus
TH16 [] MD Bus
REP [] Diags
TH18_0 [] LCD Driver
TH19 [] Firmware Revision
INTEG check code integrity
CRASH crash system
VER SW version
G Flip back to the trusty "G" interpreter; same as <ctrl D>
DEBUG [] Stuff which should probably be somewhere else
HEAP [] Heap diags
MOS [] Operating system diagnostics
FILES Show file task ids
REPort [] Diagnostic reporting
CMD>
Now, it’s probably the best time for the traditional disclaimer: you may break things here, I’m not responsable for anything.

Bonne vue d’ensemble de l’interface interne de Nucleus. grâce à votre examen, j’ai restauré le nouveau SSL Nucleus2 acheté sur Ebay. cependant, j’ai dû bricoler avec l’étude du micrologiciel pour surveiller le port série via MacOS pendant que l’ordinateur était configuré avec le port D’Sub9.
