1. Whai muri i te whakahoahoa i te rama SPI, huri i te whakahuri DIP SW5-1 ki te OFF. Ko tenei kowhiringa ka whakaoho i te tukatuka Cortex-M3 mai i te mahara DDR.
2. Patohia te SW6 hei tautuhi i te taputapu SmartFusion2. Ka kapehia e te miihini whawhai te ahua tono mai i te rama SPI ki te mahara DDR ka tukuna te tautuhi ki a Cortex-M3, e mau ana i te ahua tono mai i te mahara DDR. Mena ko te whakaahua kua whakaratohia "sample_image_LPDDR.bin” ka utaina ki te SPI flash, ka whakaatuhia e te papatohu rangatū nga karere powhiri, te whakahuri i te haukoti (penei i te SW2, i te SW3 ranei) me nga karere aukati matawā, pera i te Whakaaturanga 17 ka whakaatuhia he tauira LED rere i runga i te LED1 ki te LED8 i runga i te SmartFusion2 Kete Aromātai Haumarutanga.

Whakamutunga
Kua angitu koe i te whakamahi i te SmartFusion2 SoC FPGA me te whakamarumaru waehere mai i te SPI Flash ki te mahara LPDDR. Ko tenei whakaaturanga e whakaatu ana i te kaha o te taputapu SmartFusion2 ki te atanga ki te mahara DDR me te whakahaere i te ahua ka taea te whakahaere mai i te mahara DDR ma te whakamarumaru waehere mai i te taputapu mahara flash SPI . E whakaatu ana hoki i nga tikanga e rua mo te whakatinanatanga whakamarumaru waehere i runga i te taputapu SmartFusion2.

Tāpiritanga: Te Whakaputa Ipu Whakahaere File

Ko te ipu kawe file e hiahiatia ana ki te whakarite i te rama SPI mo te whakahaere i te tohu tohu whakamarumaru waehere. Hei whakaputa i te ipu kawe file mai i “sample_image_LPDDR” SoftConsole, mahia nga mahi e whai ake nei:

1. Hangaia te kaupapa SoftConsole me te hanga tuhinga hono-whakamahi-i-wahi-wahoDDR.
2. Tāpirihia te ara whakaurunga SoftConsole, hei tauiraample,
   C:\Microsemi\Libero_v11.7\SoftConsole\Sourcery-G++\bin, ki te 'Taupepa Taiao', pera i te Whakaaturanga 21.
