element14 WaRP7
|
||||
===============
|
||||
|
||||
This CPU card is based on an NXP i.MX7S SoC.
|
||||
|
||||
Supported hardware
|
||||
==================
|
||||
|
||||
- NXP PMIC PFUZE3000
|
||||
- Kingston 08EMCP04-EL3AV100 eMCP (eMMC and LPDDR3 memory in one package)
|
||||
- 8 GiB eMMC Triple-Level cell NAND flash, eMMC standard 5.0 (HS400)
|
||||
- 512 MiB LPDDR3 SDRAM starting at address 0x80000000
|
||||
|
||||
Bootstrapping barebox
|
||||
=====================
|
||||
|
||||
The device boots in internal boot mode from eMMC and is shipped with a
|
||||
vendor modified u-boot imximage.
|
||||
|
||||
Barebox can be used as a drop-in replacement for the shipped bootloader.
|
||||
|
||||
The WaRP7 IO Board has a double DIP switch where switch number two defines the
|
||||
boot source of the i.MX7 SoC:
|
||||
|
||||
+-----+
|
||||
| |
|
||||
| | O | <--- on = high level
|
||||
| | | |
|
||||
| O | | <--- off = low level
|
||||
| |
|
||||
| 1 2 |
|
||||
+-----+
|
||||
|
||||
Bootsource is the internal eMMC:
|
||||
|
||||
+-----+
|
||||
| |
|
||||
| O | |
|
||||
| | | |
|
||||
| | O | <---- eMMC
|
||||
| |
|
||||
| 1 2 |
|
||||
+-----+
|
||||
|
||||
Bootsource is the USB:
|
||||
|
||||
+-----+
|
||||
| |
|
||||
| O O | <---- USB
|
||||
