# BIOS
|
|
|
|
This repository includes official releases and beta versions of BIOS for various branches, as well as related tools.
|
|
|
|
- ⚠ Generally, you should only upgrade the BIOS of the same branch. Cross-branch upgrades should only be performed when testing different BIOS features.
|
|
- ⚠ Upgrading the BIOS across different branches may invalidate the Secure Boot keys.
|
|
- ⚠ Upgrading to the incorrect BIOS branch may result in some functions of the carrier board not working properly.
|
|
- ⚠ BIOS files under `Carrier-Boards` are designed exclusively for the specific carrier boards. Do NOT flash them onto a LattePanda Mu paired with any other carrier board or no carrier board.

## Naming Rule
|
|
|
|
### New Naming Scheme (2025-12 and later)
|
|
|
|
**Format**
|
|
`S70NC1R200-[Memory]-[Version][-Variant].bin`
|
|
|
|
- **S70NC1R200**: Platform identifier (LattePanda Mu N100/N305)
|
|
- **Memory**:
|
|
- `8G` = 8GB RAM
|
|
- `16G` = 16GB RAM
|
|
- **Version**:
|
|
- `A`, `B`, `C`... (incremented alphabetically for each new release)
|
|
- **Variant** (optional):
|
|
- *(no suffix)* = Default (PCIe)
|
|
- `SATA` = SATA branch
|
|
|
|
**Examples**
|
|
|
|
- `S70NC1R200-8G-A.bin` → 8GB, Default (PCIe)
|
|
- `S70NC1R200-16G-A-SATA.bin` → 16GB, SATA
|
|
|
|
**Notes**
|
|
|
|
- New scheme is simplified and user-oriented.
|
|
- **All subsequent updates will follow this naming convention.**
|
|
|
|
### Legacy Naming Scheme (2024 Initial Release)
|
|
|
|
**Format**
|
|
`LP-BS-S70NC1R200-[Rank]-[Version][-Variant].bin`
|
|
|
|
- **LP**: LattePanda
|
|
- **BS**: BIOS
|
|
- **S70NC1R200**: Platform identifier(LattePanda Mu N100/N305)
|
|
- **Rank**:
|
|
- `SR` = Single Rank (corresponds to 8GB models)
|
|
- `DR` = Dual Rank (corresponds to 16GB models)
|
|
- **Version**:
|
|
- `A`, `B`
|
|
- **Variant**:
|
|
- *(no suffix)* = Default (PCIe)
|
|
- `SATA` = SATA branch
|
|
|
|
**Example**
|
|
|
|
- `LP-BS-S70NC1R200-SR-B.bin` → 8GB, Default (PCIe)
|
|
|
|
- `LP-BS-S70NC1R200-DR-B-SATA.bin` → 16GB, SATA
|
|
|
|
### Mapping: Legacy → New Naming
|
|
|
|
- `SR` → `8G`
|
|
- `DR` → `16G`
|
|
|
|
**Examples**
|
|
|
|
- `LP-BS-S70NC1R200-SR-B.bin` → `S70NC1R200-8G-A.bin` (newer)
|
|
- `LP-BS-S70NC1R200-DR-B-SATA.bin` → `S70NC1R200-16G-A-SATA.bin` (newer)
