Part Number: TMDS243GPEVM
I'm trying to add flash support to my project (FreeRTOS, two tasks, one ISR (triggered by ADC0)).
In Sysconfig I have added the Flash driver from the TI BOARD DRIVERS section. From the ospi_flash_io example I have taken the function calls to read, erase and write.
Flash acces happens in the lowest priority task.
Reading from flash appears to work:
Flash_read(gFlashHandle[CONFIG_FLASH0], offset, (uint8_t *) ¶_save_hdr, spi_p_size);
where offset is 0x200000.
The write sequence is as follows:
Flash_offsetToBlkPage(gFlashHandle[CONFIG_FLASH0], offset, &blk, &page);
Flash_eraseBlk(gFlashHandle[CONFIG_FLASH0], blk);
// Flash_write(gFlashHandle[CONFIG_FLASH0], offset, (uint8_t *) &spi_para_start, spi_p_size);
As soon as I uncomment the call to Flash_write() I end up in HwiP_data_abort_handler(void) in HwiP_armv7r_handlers_freertos.c.
Any hints on what I could be doing wrong would be appreciated.
Best regards,
Johannes
