| # Here are the steps to uprev the PS8745 firmware. |
| # |
| # 1) Unzip the .zip file emailed from the vendor. |
| # 2) Convert from hex to bin. |
| # ex: objcopy -I ihex --output-target=binary \ |
| # --gap-fill 0xff --pad-to 0x10000 \ |
| # PS8745_FW_0x02_20220622_A2_whole.hex \ |
| # parade-ps8745a2-firmware-2/ps8745_a2_0x02.bin |
| # 3) Tarball it up using XZ, including the right directory. |
| # ex: tar -cJf parade-ps8745a2-firmware-2.tar.xz \ |
| # parade-ps8745a2-firmware-2/ps8745_a2_0x02.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 access", |
| # click on ADD ENTRY, then set: |

| # Access: "Reader" |
| # 6) Finally run 'ebuild parade-ps8745a2-firmware-2.ebuild manifest' |
