Philipp Ebensberger	87f97e490c	mimxrt/sdcard: Implement SDCard driver. ... - Configures `PLL2->PFD0` with **198MHz** as base clock of `USDHCx` peripheral. - Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD` - Adds creation of pin defines for SDCard to make-pins.py - Adds new configuration option for SDCard peripheral pinout to mpconfigport.h - Adds interrupt handling support instead of polling - Adds support for `ADMA2` powered data transfer - Configures SDCard to run in HS (high-speed mode) with **50MHz** only! SDCard support is optional and requires `USDHC` peripheral. Thus this driver is not available on `MIMXRT1010_EVK`. SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1` in mpconfigboard.mk. Signed-off-by: Philipp Ebensberger	2021-09-07 20:45:33 +02:00
robert-hh	1074c784b0	mimxrt: Add support for Hyperflash chips. ... Hyperflash is used by the MIMXRT1050_EVKB, MIMXRT1060_EVK and MIMXRT1064_EVK boards. This commit includes: - add support for Hyperflash - modify MIMXRT1060_EVK and MIMXRT1064_EVK to change from QSPI to hyperflash. - minor incidental changes to other boards so they still build Note: Erasing a sector on the hyperflash is slow. It takes about a second, which seems too long, but matches the data sheet.	2021-07-31 16:25:40 +10:00
robert-hh	53fea8598e	mimxrt/boards: Add board configuration files for Teensy 4.1. ... These are at the moment more or less identical to the Teensy 4.0 files, except for the pins.csv file and the flash size.	2021-06-04 01:00:39 +10:00
