Subject: [RFC 0/4] Run barebox on sc6531e-based feature phone
Date: Sat, 10 Jun 2023 13:32:16 +0300 [thread overview]
Message-ID: <20230610103220.566369-1-antonynpavlov@gmail.com> (raw)
This patch series adds initial support for SC6531E chip.
SC6431E chip is specially designed solution for creating
feature phones. It contains
* ARM926EJ-S core (up to 208 MHz)
* embedded PSRAM
* peripherals: USB, SPI, UART, IIS, PCM, I2C, keypad, LCD
* SIM card and GSM/GPRS/FM/BT stuff
This work is based on FPDoom, see [1], [2], [3] for details.
At the moment only timer and debug_ll output via USB
are supported.
After adding lcd and keypad driver running bareDOOM [4]
on SC6531E will be possible.
