| # Here are the steps to uprev the PS8705 firmware. |
| # |
| # 1) Unzip the .zip file emailed from the vendor. |
| # 2) Convert from hex to bin. |
| # ex: objcopy -I ihex --output-target=binary PS8705_FW_0x04_20200930_A4.hex \ |
| # parade-ps8705a3-firmware-4/ps8705_a3_0x04.bin |
| # 3) Tarball it up using XZ, including the right directory. |
| # ex: tar -cJf parade-ps8705a3-firmware-4.tar.xz \ |
| # parade-ps8705a3-firmware-4/ps8705_a3_0x04.bin |
| # 4) Then upload it at https://pantheon.corp.google.com/storage/browser/chromeos-localmirror/distfiles |
| # 5) On the uploaded file, click the three-dot-menu, "Edit Permissions", and |
| # add a new entry for Public "allUsers" with Reader permission. |
| # 6) Finally run `ebuild parade-ps8705a3-firmware-4.ebuild manifest` |
