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
