Switch - hekate v5.8.0 & Nyx v1.3.0

Recommended Posts


Supports booting ALL current CFWs, Android/Linux booting and payload tools.
No more SD card removals

Supports: Erista and Mariko units

Latest HOS supported: 14.1.2

hekate 5.8.0 changes

  • Better backlight control for Aula OLED panel
  • Fixed an issue where Nyx would fail to load after a failed attempt of chainloading a payload
  • Added watchdog timer to protect against hangs from SD corruption when loading and running LP0/Minerva configuration
    Now if the libraries are corrupted and are executed, it will fire the watchdog after 5s if BPMP hangs and reload and skip them
  • Fixed a bug in low battery monitor where it could deinit display 2 times.
  • Various BDK (HW) changes that are propagated to hekate main (aka under the hood improvements)

Notice about Atmosphere 1.0.0 and up: The fss0=atmosphere/fusee-secondary.bin in hekate_ipl.ini must be changed to fss0=atmosphere/package3. And make sure that atmosphere/contents folder does not have old Atmosphere components.
Notice about resized emuMMC: Resized emuMMC does not have the slow bug anymore. You can create a new one or recreate it via Nyx and the issue will be gone.

Nyx v1.3.0 Changes

  • Add support for 5 entries per line in Launch/More Configs for a total of 10 entries
    A new button called Extended Boot Entries is available in Nyx options
  • Support for grey background box removal on launch entries was added
    To remove it, the icon must be named as *_nobox.bmp. This also allows custom made ones built into the icon for better theming support.
  • The 2 features above can be viewed in #739
  • emuMMC backup now uses backup/{emmc_sn}/emummc folder instead of default in order to keep it separate
  • Switch Lite gamepad (Sio) support
  • Hori gamepads on Switch OLED support
  • Improved Joycon communication.
    Now USB gamepad will behave better. Virtual mouse will not drift (if drift is not an issue). And lastly, BT pair dumping should always succeed first try, if it finds HOS pairings, unlike before where it sometimes failed to find these.
  • Fix archive bit tool now guards against corrupted sd cards, in order to avoid hangs
    It now also reports errors when trying to access folders or fixing archive bits
  • Partition Manager's Backup/Restore now guards against corrupted sd cards, in order to avoid hangs
  • Partition Manager now offers a full wipe, in case it can backup contents.
  • Partition Manager now backups Mariko Warmboot Storage folder if it can't do a full backup. (Previously it would only backup the bootloader folder).
  • Fix Hybrid MBR button now also clears hidden Windows attributes for MBR or GPT schemes and also checks if MBR has a GPT partition, in order to avoid revival of dead GPT.
  • Added support for showing info and getting proper ipatches dumps on T210B01 (Mariko)
  • Added info about the new Hynix DRAM chip
  • microSD info now also shows total size of FAT partition
  • Various BDK (HW) changes that are propagated to hekate main (under the hood improvements)

BDK Changes

  • Display: A full refactor of the Display Interface driver was done
    Deduplicates various configs and also brings full support for Samsung OLED panel with proper backlight control and color management. Additionally, that saves around 1KB of payload space.
  • SDRAM: Deduplicated dram config patches to save binary space
  • Regulator 5V: Added support for Hoag and Aula
  • Fan: Added support for Hoag and Aula
  • s_printf now prints negative numbers if %d is used. Additionally it is now checked for format errors.
    Note: 64bit types are still not supported. Cast them to 32bit equivalent and print them in parts).
    Any code that manually handles negative numbers should remove that part.
  • UART: Driver now supports manual and auto HW flow control and 2 STOP bit support for higher baudrates
    BREAKING: uart_wait_idle function was renamed to uart_wait_xfer and uart_print to uart_printf to reflect on what they do.
  • Joycon: Driver was refactored and now supports Switch Lite
    The refactoring also brought improved communication and fixed various issues when interfacing with them.
  • SDMMC: Fixed an issue where eMMC lower speeds would register as HS200 instead of lower
  • SDMMC: Exposed get CSD and SCR functions.
  • USB2: Stack now behaves better when RAM is slow
  • XUSB: Improved power down
  • USB2/XUSB: Do proper deconfigure of endpoints when host asks that
  • Heap info was extended with nodes used and total nodes.
  • Ini: Added proper ini free function (ini_free)
  • List: Added backwards traverse macros for lists
  • Tmr/WDT: Added timer/watchdog driver and also moved all timer/sleep functions into it
  • IRQ: Added FIQ watchdog handling with BDK_WATCHDOG_FIQ_ENABLE. Setting BDK_RESTART_BL_ON_WDT also, causes a reload of bootloader on FIQ

  • How to use Partition Manager for Linux/Android?
    For L4T Linux you can use the official Ubuntu Bionic 3.4.0 or newer release or any other distro betas.
    For android you need to build Android P or Q which support/require the new partition scheme.

  • My Joy-Con drift when in Nyx, how to fix?
    Nyx applies an auto calibration at boot. That happens when you hear the rumble. If you press the sticks before, then a wrong calibration will get applied.
    To fix that on the fly, simply remove the Joy-Con and re insert it. This always causes a new calibration. Just make sure you don't touch the stick when you reinsert.

  • I don't care about emuMMC/Linux/Android. Can the Part manager be used for something else?
    Yes. You can still reformat your SD card to a single FAT32 partition.
    You can even use it when you have exFAT and you want to format to FAT32.
    It is also suggested to format your sd card via hekate. That's because it prepares it for performance. something that many partitioning tools neglect.


Check readme.md for more.

For maximum performance of UMS in Windows, you need to run nyx_usb_max_rate__run_only_once_per_windows_pc.reg, only once per PC you have.
It only affects hekate's usb device. You can also view that file with text editor and see what it does. Linux/Mac OS users do not need that.

How to update:

  • Drag n drop bootloader folder into sd card root and hit merge/replace.
    No need to delete that folder first, especially if you want your configs and payloads.
  • You can choose to update your RCM injection device or PC with the new hekate_ctcaer_x.x.x.bin or not.
    In any case, bootloader/update.bin, will be checked and if newer it will get loaded.
    update.bin is hekate and it is already copied with the bootloader folder drag n drop update process.

Notice about Atmosphere 1.0.0 and up: The fss0=atmosphere/fusee-secondary.bin in hekate_ipl.ini must be changed to fss0=atmosphere/package3. And make sure that atmosphere/contents folder does not have old Atmosphere components.
