    Paul Singh
    Hi, Is it always necessary to check for the busy state of I2C bus? evmomapl138 BSL’s I2C_Read() has a parameter chk_busy to determine whether to check for bus busy, and in most usage this is skipped by setting chk_busy­ as #define SKIP_BUSY_BIT_CHECK (0) I2C_read() skips BB...

    John Grant
    Hi, We follow the steps detailed in 10.7.4 C674x Megamodule Clock ON/OFF of SPRUH77 and tries to implement DSP sleep function without using BIOS or Linux PSP. The expectation is that ARM repeatedly put DSP into sleep first, waits for 5 seconds, then wakes it up, and repeats this cycle. The interrupt...

    Paul Singh
    Hi, Because of the formula of “SPRUH77 10.2 Power Consumption Overview” gives dynamic power as proportional to voltage square and to frequency, I then worked on minimizing both voltage and frequency. With regard to frequency there are two approaches: (1) PSC off, which complete gates...

    Hi, I want to change PINMUX assignments on the fly during Linux running. As it is not that difficult in DSP on OMAPL137/ 138 I used similar idea on Linux, possibly without writing kernel mode driver. My idea is that i will use /dev/mem interface and mmap function to map PINMUX registers and KICK...
