Example Project which uses all three Memory-Areas

Masmiseim — Tue, 09 Oct 2018 09:14:22 GMT

Hello,

are there any examples which run out from Hyperflash (code execution), don’t use the SD-RAM and use all three internal RAM areas (ITCM + DTCM + OCRAM). I’m searching for an example for IAR. I’m only interested in the memory-Configuration (*.icf File) and Startup-Code.

All the examples I’ve seen in the SDK use only the TCM or the SD-RAM.

Thanks and Regards

Hi Makus,

There are many MCUXpresso SDK demo code allocate code in Flash, and data in DTCM or OCRAM. For example, MIMXRT1052xxxxx_flexspi_nor.icf under IAR hello world demo.

define symbol m_interrupts_start = 0x60002000;

define symbol m_interrupts_end = 0x600023FF;

define symbol m_text_start = 0x60002400;

define symbol m_text_end = 0x63FFFFFF;

define symbol m_data_start = 0x20000000;

define symbol m_data_end = 0x2001FFFF;

define symbol m_data2_start = 0x20200000;

define symbol m_data2_end = 0x2023FFFF;

Have a great day,
TIC
