* ARM: save and print exception contextHEADmasterBen Gras2016-06-203-23/+201
| | | | | | | | | | | | | | | | Debugging aid. Prints nice exception context info like: R0 = 0x00000000 R8 = 0x402fe8b0 R1 = 0x402ffd80 R9 = 0x40309b15 R2 = 0x00000800 R10 = 0x00000000 R3 = 0x402ffd40 R11 = 0x00000000 R4 = 0x402ffd40 R12 = 0x402fdd38 R5 = 0x402ffd80 SP = 0x40309694 R6 = 0x00000003 LR = 0x402fa348 R7 = 0x00000800 PC = 0x402f8614 VEC = 0x00000003 Data structures, definitions and code taken from RTEMS.
* FAT fs changes: FAT code and larger ROM sizeBen Gras2016-06-205-4/+2420
| | | | | | | | | | | | | | . add fatfs umon cli to it. unmodified from the umon 1.19 distribution, apache-licensed. . also add dosfs from the umon 1.19 distribution, which is similarly liberally licensed. . increase available 'ROM' size to 128kB minus 1kB secure + 18kB reserved (numbers from uboot wiki). . no unaligned access - needed to access fields in on-disk structs without gcc generating unaligned access instructions (causes data abort exceptions) . turn on shellvars for BBB as they are needed to connect FATFS to the SD i/o functions

* BBB: Migrate MMC0 clock enable from am335x_sd.c:sdInit() to cpuio.c:initCPUio()Jarielle Catbagan2015-08-042-4/+4
| | | | | | The reason why the MMC0 clock enable has to be executed much earlier is a result of the invocation of sdInstalled() in sd.h before sdInit(). Without this migration, an exception occurs since the MMC0 interface has not been enabled before it is accessed by sdInstalled().

| | | | | | | | | | | UART booting sd_setup.sh is a script that automates the process of setting up an SD card with the appropriate uMon image to boot using either "raw" or FAT mode. README currently documents the steps required to boot the Beaglebone Black from an SD card or via UART.

| | | | | | | | | | An MLO file will be created from the concatenation of a corresponding GP header and the uMon image. A GP header must be prepended to the uMon image when booting from non-XIP devices. Refer to the AM335x TRM, Section 26.1.9 for more information. These type of images have been tested when booting the MLO file from an SD card with a FAT32 primary partition marked as Active.
