New page

== Updating 393 cameras FPGA bitstream versions after code modifications ==
=== Modifications to the SATA code ===
SATA controller subsystem source code is maintained in a [https://git.elphel.com/Elphel/x393_sata x393_sata] repository.
1. Edit py393sata/create_ahci_registers.py and modify [https://git.elphel.com/Elphel/x393_sata/blob/master/py393sata/create_ahci_registers.py#L35 RID value]

2. Run ''create_ahci_registers.py''

It will finish with lines similar to these:
AHCI register defaults are written to /home/eyesis/git/elphel393/fpga-elphel/x393_sata/includes/ahci_defaults.vh
AHCI register bit field types are written to /home/eyesis/git/elphel393/fpga-elphel/x393_sata/includes/ahci_types.vh
AHCI localparam definitions are written to /home/eyesis/git/elphel393/fpga-elphel/x393_sata/includes/ahci_localparams.vh

3. Commit changes to the git repository

4. Copy SATA-related files (including new autogenerated ones) to x393 file tree by running
''./copy_x393_sata.sh'' in the x393 folder. Relative path to SATA files is assumed to be ../x393sata - it is set up when installing all the software with [[Development_for_10393 | elphel393/setup.py]]
=== Modifications to the x393 code ===
FPGA version number is generated from the [https://git.elphel.com/Elphel/x393/blob/master/fpga_version.vh#L38 fpga_version.vh] and it can be read in the camera at runtime as a 32-bit number. Version is stored as 0x0393VVVV, where VVVV is a 4-digit hex number (will try to keep it as 2 digits for major version/branch, and 2 lower for the incremented minor number).

# Increment the number
# Run implementation tools
# Verify timing ((now small errors are OK as the settings are for speed grade "-1", hardware is "-2")
# Copy result x393_parallel.bit from vivado_results to the root folder
# Verify bitsteram with the hardware
# Commit to git repository
