It's been awhile since sharing his decrypted sl-config.xml.env, and following past PS4 UART updates and PS4 Hardware Pinouts today PlayStation 4 developer qwertyoruiopz posted some pictures of his latest PS4 UART to DCSD project on Twitter!
From the related Tweets below, it appears he's using hardware and mapping techniques while working on dumping PlayStation 4 UART debug logs and may end up bruteforcing commands via the syscon UART as suggested by VVildCard777 in hopes to obtain more information on the PS4 system controller for developers.
Using DCSD as generic UART to USB. Easy to do without soldering by just sticking jumpers in the hot glue.
Not too shabby of a solder job. Here's to hoping the PS4 still boots!
PS4 UART to DCSD (earlier tweet typod USB instead of UART)
And PS4 actually boots! Ayy
Dumping flash?
UART
UART.
I see you have syscon uart connected there, planning on bruteforcing commands? had no luck with it yet myself, need to make a good go of it.
i have waaay more than 7 leftover lool. I just put in bare minimum to hold everything together more or less.
I just connected both because I don't really wanna open the PS4 again. But after looking into it it sounds interesting.
i kinda overheateded the board with the soldering iron tip on one point. maybe some trace could have gotten damaged. thankfully not
Because I don't have any handy and got plenty of DCSD
uart enabler for 4.05
right, i only solder 1 wire (tx on ps4) and attach gnd wire to hdd cage, then using like 5$ uart to usb i listen on arduino(serial montor). very simple.
Thanks to @ArthurBishop, @Chaos Kid and @raedoob in the PSXHAX Shoutbox for the heads-up!

Code:
uint16_t *securityFlags = (uint64_t *)(kernel_base+0x2001516); *securityFlags = *securityFlags & ~(1 << 15); *(char *)(kernel_base + 0x186b0a0) = 0;
