The Vivado install root differs per machine (C:\Xilinx here, D:\Xilinx on the box these skills were written on), so every hardcoded path was already wrong on this machine. - new fpga_flash/scripts/vivado_env.py: resolves --vivado-dir > env var > VIVADO_ROOT (falling back to VIVADO_PATH) from ~/skills_env.md - gen_mcs / program_flash / check_flash_csv: --vivado-dir now optional - fpga_update/gen_update_mcs.py: same precedence for --vivado - fpga_flash / smod_atsc_dev / vivado-prj-create SKILL.md: document the lookup instead of naming a drive letter - skills_env template: VIVADO_ROOT/VIVADO_PATH are now blanks to fill in, so a new machine can't inherit a wrong default Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Step 1: Check and update Vivado Flash device CSV to include w25q128bv.
|
|
|
|
Checks whether 'w25q128bv-spi-x1_x2_x4' is present in Vivado's
|
|
xicom_cfgmem_part_table.csv. If not, appends the correct row.
|
|
|
|
Usage:
|
|
python check_flash_csv.py # Vivado path from ~/skills_env.md
|
|
python check_flash_csv.py --vivado-dir "<install root>" # or override it
|
|
|
|
Exit codes:
|
|
0 = device already present (no changes made)
|
|
2 = device was successfully added (Vivado restart required)

1 = error (CSV not found or write failure)
