3 | The Mediatek MT6253 is a relatively modern baseband SoC made by Taiwan-based Mediatek. |
||
4 | |||
5 | It inherits a lot from the older series of MT622x SoCs, but provides 2 DSP cores, RF module and power management block on the chip. |
||
6 | |||
7 | The chip uses different addresses for periph. bus compared to it's predecessors. |
||
8 | |||
9 | = ROM Bootloader = |
||
10 | |||
11 | The chip contains ROM bootloader similar to [wiki:MT6253]. |
||
12 | |||
13 | In order to keep the chip powered-on, PMIC registers need to be set-up properly. |

15 | == DSP communication == |
||
16 | Baseband communication is handled by DSP #1. |
||
17 | |||
18 | === DSP initialization === |
||
19 | |||
20 | * Power ON DSP |
||
21 | * Wait |
||
22 | * Install patch data |
||
23 | * Write some data via IDMA |
||
24 | * Wait for correct data in DSP1_SharedMem |
||
25 | |||
26 | Communication between ARM and DSP is carried via DSP1 Shared memory region and DSP1 shared registers. Initialization uses also IDMA. |
||

28 | == Usage in mobile phones == |
