2019-02-06Fix UART examples for Colibri iMX7colibri-imx7-m4-freertos-v8Andy Kiser
The uart_polling and uart_interrupt examples were originally written for a UART used in DCE mode. The Colibri iMX7 is designed to use the UART in DTE mode. The signals are swapped between DTE and DCE (Rx <-> Tx, and control signals). In order to use the correct pin direction, the bit DCEDTE in the UARTx_UFCR register needs to be configured accordingly.

2018-08-30use -Og for debuggingStefan Agner
Currently we use -O0 (no optimization) for debug builds. Unfortunately this leads to large firmwares really quickly, and prevents debugging in TCM/OCRAM. Use -Og which enables some optimization which do not interfere with debugging. GCC manual says: Optimize debugging experience. -Og enables optimizations that do not interfere with debugging. It should be the optimization level of choice for the standard edit-compile-debug cycle, offering a reasonable level of optimization while maintaining fast compilation and a good debugging experience.

2017-05-16force program header alignment to be smaller than 32kbytesStefan Agner
GCC 5 and newer seem to choose higher alignment values in elf program headers than older versions. This causes issues when doing address translations with areas which have lower alignment: It moves the base address outside of memory base addresse (e.g. TCML memory base address is aligned to 32kiB). With 4K we use a safe and sensible value for alignment. With that all elf program headers are aligned with 0x1000. $ readelf -l debug/hello_world.elf Elf file type is EXEC (Executable file) Entry point 0x1fff8311 There are 3 program headers, starting at offset 52 Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x001000 0x1fff8000 0x1fff8000 0x00240 0x00240 R 0x1000 LOAD 0x001240 0x1fff8240 0x1fff8240 0x03904 0x03904 RWE 0x1000 LOAD 0x005000 0x20000000 0x1fffbb44 0x00070 0x059b0 RW 0x1000 Signed-off-by: Stefan Agner <stefan.agner@toradex.com>
2017-05-16use OCRAM_S for interrupt vectors by defaultStefan Agner
The Cortex-M4 core starts executing at 0x00000000, which is OCRAM_S. So far the bootloader (bootaux) copied the reset vector and the initial stack pointer to that location, however, this does not work well when using debuggers. Also, newer U-Boot support elf loading, which allow to load the reset vector directly to the right location. It also safes some bytes in the area where the firmware is stored. This basically mandantes to use elf files since bin firmware files can not be sparse... Hence disable building bin files by default. Preserve the old linker files with _bin extension in case bin files are still preferred. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>

2016-11-14examples/imx7_colibri_m4: select correct clock for GPTAStefan Agner
GPTA is supposed to run directly of the 24MHz OSC. Fix a type which update GPTB's root clock instead of GPTA. Note: GPTB seems to rely on the System PLL PFD0, which seems to be influenced by Linux' SDHC driver. Freezes of both systems have been observed. Disabling the SDHC driver on the Linux side or using the 24MHz clock source for GPTB seem to avoid freezes. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>
