| # Here are the steps to uprev the ANX3447 firmware. |
| # |
| # 1) Unzip the .zip file obtained from the vendor. |
| # 2) Convert from hex to bin. |
| # ex: objcopy -I ihex --output-target=binary \ |
| # --gap-fill 0xff --pad-to 0xE000 \ |
| # Liberty_tcpc_v0.1.15.hex \ |
| # analogix-anx3447-firmware-0.1.15/anx3447_ocm_0x0115.bin |
| # 3) Tarball it up using XZ, including the right directory. |
| # ex: tar -cJf analogix-anx3447-firmware-0.1.15.tar.xz \ |
| # analogix-anx3447-firmware-0.1.15/anx3447_ocm_0x0115.bin |
| # 4) Follow https://chromium.googlesource.com/chromiumos/docs/+/HEAD/archive_mirrors.md#getting-files-onto-localmirror |
| # to upload the zipped file. |
| # 5) Finally run 'ebuild analogix-anx3447-firmware-0.1.15-r1.ebuild manifest' |
