### Verify BrcmPatchRAM Installation

Source: https://github.com/acidanthera/brcmpatchram/blob/master/README-Mac.md

Check the system log for BrcmPatchRAM output during startup to confirm successful installation and operation. This command filters logs for lines containing 'brcm' or 'brcmf'.

```bash
sudo cat /var/log/system.log | grep -i brcm[fp]
```

### Extracting Device ID from .inf File

Source: https://github.com/acidanthera/brcmpatchram/blob/master/README.md

This example shows how to locate a specific device's vendor and product ID within a Windows driver's .inf file, which is crucial for identifying the correct firmware.

```dosini
%BRCM20702.DeviceDesc%=BlueRAMUSB0223, USB\VID_0930&PID_0233       ; 20702A1 Toshiba 4352
```

--------------------------------

### Recommended boot arguments for wake from sleep issues

Source: https://github.com/acidanthera/brcmpatchram/blob/master/README.md

Provides a set of kernel boot arguments that have been reported to resolve typical "wake from sleep" problems with Bluetooth devices.

```bash
bpr_probedelay=100 bpr_initialdelay=300 bpr_postresetdelay=300
```

--------------------------------

### Compressing Firmware with zlib.pl

Source: https://github.com/acidanthera/brcmpatchram/blob/master/README.md

This command uses the provided zlib.pl script to compress a firmware hex file, reducing its size and preparing it for use with BrcmPatchRAM.

```bash
zlib.pl deflate BCM20702A1_001.002.014.1443.1457.hex > BCM20702A1_001.002.014.1443.1457.zhx
```

--------------------------------

### Alternative longer delays for wake from sleep issues

Source: https://github.com/acidanthera/brcmpatchram/blob/master/README.md

Offers an alternative set of kernel boot arguments with slightly longer delays, which may also help resolve "wake from sleep" problems.

```bash
bpr_probedelay=200 bpr_initialdelay=400 bpr_postresetdelay=400
```

--------------------------------

### Identifying Firmware Files in .inf

Source: https://github.com/acidanthera/brcmpatchram/blob/master/README.md

This snippet demonstrates how to find the list of associated firmware files for a specific device within the .inf file, helping to identify the correct firmware hex file to extract.

```dosini
;;;;;;;;;;;;RAMUSB0223;;;;;;;;;;;;;;;;;
[RAMUSB0223.CopyList]
bcbtums.sys
btwampfl.sys
BCM20702A1_001.002.014.1443.1457.hex
```

--------------------------------

### Creating Hex Dump for Plist Editor

Source: https://github.com/acidanthera/brcmpatchram/blob/master/README.md

This command converts the compressed firmware file into a hex dump format, suitable for pasting into a plist editor when configuring firmware keys.

```bash
xxd -ps BCM20702A1_001.002.014.1443.1457.zhx|tr '\n' ' ' > BCM20702A1_001.002.014.1443.1457.dmp
```

### System log filtering for BrcmPatchRAM issues

Source: https://github.com/acidanthera/brcmpatchram/blob/master/README.md

Provides commands to filter system logs for BrcmPatchRAM-related messages, useful for troubleshooting firmware update failures. Use the appropriate command based on your macOS version.

```bash
# For 10.12 and newer:
log show --last boot | grep -i brcm[fp]
```

```bash
# For older macOS versions:
cat /var/log/system.log | grep -i brcm[fp]
```
