- JC 11:48 AM PCB Development: RE: RTC Crystal Specifications
- Theres a 24MHz crystal between XTALOUT and XTALIN on the ARM. Its frequency tolerance at 25C is +/- 25ppm.
Note these numbers are based on a 3359-GX-226-RL RevD. - CL 11:42 AM PCB Development: RE: RTC Crystal Specifications
- Great, thank you for the information. Is it a similar specification for the other oscillator on the board, connected to the ARM?
- JC 11:31 AM PCB Development: RE: RTC Crystal Specifications
- For the 32khz crystal attached between the OSC32KOUT and OSC32KIN pins, according to its datasheet, the frequency tolerance at 25C is +-10ppm.
- What are the ppm drift specifications for the TPS65910 RTC crystal?

- AB 04:10 PM Software Development: RE: Communicating with an 8-bit parallel interface (GPIO, SPI or GPMC)
- Updated question(s) from the customer:
I've been looking into using GPMC. The Technical Reference Manual for the AM335x says that GPMC has a 512MB address space. Since the module I have has a 512MB NAND flash on GPMC, configuring anot...
