There is the possibility to set a malloc area inside SPL:
CONFIG_SYS_SPL_MALLOC_START CONFIG_SYS_SPL_MALLOC_SIZE you do not need a lot of space, and you can try to put it inside the IRAM.
This should guarantee that spi_alloc_slave() works.
So I tried moving them to the internal RAM:
--- a/include/configs/imx6_spl.h +++ b/include/configs/imx6_spl.h @@ -70,8 +70,8 @@ #else #define CONFIG_SPL_BSS_START_ADDR 0x18200000 #define CONFIG_SPL_BSS_MAX_SIZE 0x100000 /* 1 MB */ -#define CONFIG_SYS_SPL_MALLOC_START 0x18300000 -#define CONFIG_SYS_SPL_MALLOC_SIZE 0x3200000 /* 50 MB */ +#define CONFIG_SYS_SPL_MALLOC_START 0x900000 +#define CONFIG_SYS_SPL_MALLOC_SIZE 0x8000 #define CONFIG_SYS_TEXT_BASE 0x17800000 #endif #endif
but still getting spi_alloc_slave() to fail.
You want to avoid this "CONFIG_SYS_SPL_MALLOC_*" stuff, as it increases the SPL size by 3kiB compared to MALLOC_F . Also, MALLOC_F needs just the base address of the malloc area to work (see my email).
Do you know the return value ?
