- 2019 with i2c mods
Flashing u-boot based on https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Updating_devkit_to_latest_MDK - JC 09:45 PM Software Development: RE: uBoot I2C Speed Command [MityDSP L138]
- By default the 2019 u-boot doesn't support multiple i2c buses. Though I was able to tweak some code to seemingly get it working, however I don't have devices on i2c1 to determine if its actually working.

- Testing the 2019 u-boot and i2c speed command does appear to be supported though I didn't scope the lines to prove it was changing speeds.

- The latest L138 RTOS SDK 06_03_00_106 for the L138 does have documentation for MCASP and a bunch of other peripherals.

- Hi Michael, I created a e2e question asking TI about MCASP support on the DSP. https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1595231/omap-l138-d...

- Jonathan,
If StarterWare/BareMetal are against the grain, please point me towards DSPBios code/examples that use McASP. Which version of DSP/BIOS are you using? When making a new project in CCS, do you tell CCS to target an OMAP-L138 or... - JC 07:27 PM Software Development: RE: Configuring OMAP-L138 peripherals from uBoot
- Hi Michael, We have only used the DSP with TI's DSPBios RTOS. It should already have abstraction layers for most of those peripherals.
