This document describes how to upload the cx2341x firmware to the card.
|
||||
|
||||
How to find
|
||||
===========
|
||||
|
||||
See the web pages of the various projects that uses this chip for information
|
||||
on how to obtain the firmware.
|
||||
|
||||
The firmware stored in a Windows driver can be detected as follows:
|
||||
|
||||
- Each firmware image is 256k bytes.
|
||||
- The 1st 32-bit word of the Encoder image is 0x0000da7
|
||||
- The 1st 32-bit word of the Decoder image is 0x00003a7
|
||||
- The 2nd 32-bit word of both images is 0xaa55bb66
|
||||
|
||||
How to load
|
||||
===========
|
||||
|
||||
- Issue the FWapi command to stop the encoder if it is running. Wait for the
|
||||
command to complete.
|
||||
- Issue the FWapi command to stop the decoder if it is running. Wait for the
|
||||
command to complete.
|
||||
- Issue the I2C command to the digitizer to stop emitting VSYNC events.
|
||||
- Issue the FWapi command to halt the encoder's firmware.
|
||||
- Sleep for 10ms.
|
||||
- Issue the FWapi command to halt the decoder's firmware.
|
||||
- Sleep for 10ms.
|
||||
- Write 0x00000000 to register 0x2800 to stop the Video Display Module.
|
||||
- Write 0x00000005 to register 0x2D00 to stop the AO (audio output?).
|
||||
- Write 0x00000000 to register 0xA064 to ping? the APU.
|
||||
- Write 0xFFFFFFFE to register 0x9058 to stop the VPU.
|
||||
- Write 0xFFFFFFFF to register 0x9054 to reset the HW blocks.
|
||||
- Write 0x00000001 to register 0x9050 to stop the SPU.
|
||||
- Sleep for 10ms.
|
||||
- Write 0x0000001A to register 0x07FC to init the Encoder SDRAM's pre-charge.
|
||||
- Write 0x80000640 to register 0x07F8 to init the Encoder SDRAM's refresh to 1us.
|
||||
- Write 0x0000001A to register 0x08FC to init the Decoder SDRAM's pre-charge.
|
||||
- Write 0x80000640 to register 0x08F8 to init the Decoder SDRAM's refresh to 1us.
|
||||
- Sleep for 512ms. (600ms is recommended)
|
||||
- Transfer the encoder's firmware image to offset 0 in Encoder memory space.
|
||||
- Transfer the decoder's firmware image to offset 0 in Decoder memory space.
|
||||
- Use a read-modify-write operation to Clear bit 0 of register 0x9050 to
|
||||
re-enable the SPU.
|
||||
- Sleep for 1 second.
|
||||
- Use a read-modify-write operation to Clear bits 3 and 0 of register 0x9058
|
||||
to re-enable the VPU.
|
||||
- Sleep for 1 second.
|
||||
- Issue status API commands to both firmware images to verify.
