Hello,
Our Setup:
i.MXRT1176
IS25LP01G Flash Devices with 1Gbit / 128Mb
We use it in individual Mode. I expected that i can access Flash A2 via address 0x38000000. A1 Range will be 0x30000000 to 0x37FFFFFF.
We connected four NOR Flash Devices on FlexSPI Port A1/A2/B1/B2. I am only able to access A1 via XIP. Try to Read via memcpy at the Address 0x38100000, which should be Chip on A2, i get values of 0x30100000 from Chip on A1. It seems XIP does not support multiple Chips? I am right?
I took a example from flexspi_nor_flash_polling and added Port selection. I can Program values to the A2 Chip. B1/B2 not tested yet.
Is it otherwise possible?
Thank you,
Florian

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) It seems Xp does not support multiple Chips?
-- No, you can access the other chips other than the A1 via the AHB bus.
Have a great day,
