The code is intended to decompress kernel, being compressed using lzma utility
|
||||
build using 7zip LZMA SDK. This utility is located in the LZMA_Alone directory
|
||||
|
||||
decompressor code expects that your .trx file consist of three partitions:
|
||||
|
||||
1) decompressor itself (this is gziped code which pmon/cfe will extract and run
|
||||
on boot-up instead of real kernel)
|
||||
2) LZMA compressed kernel (both streamed and regular modes are supported now)
|
||||
3) Root filesystem
|
||||
|
||||
Please be sure to apply the following patch for use this new trx layout (it will
|
||||
allow using both new and old trx files for root filesystem lookup code)
