4Board-specific details:
5
6MIMXRT1170_EVK:
7This board uses CONFIG_I2S_TEST_SEPARATE_DEVICES=n and connects TX and RX blocks in one
8SAI peripheral by shorting signals externally on the EVK.
9These are the HW changes required to run this test:
10 - Short BCLK J9-pin1 (SAI1_RX_BCLK) to J9-pin11 (SAI1_TX_BCLK)
11 - Short SYNC J9-pin5 (SAI1_RX_SYNC) to J9-pin13 (SAI1_TX_SYNC)
12 - Short Data J9-pin7 (SAI1_RX_DATA) to J9-pin9 (SAI1_TX_DATA)
13
14MIMXRT1170_EVKB (SCH-55139 Rev C/C1/C2):
15This board uses CONFIG_I2S_TEST_SEPARATE_DEVICES=n and connects TX and RX blocks in one
16SAI peripheral by shorting signals externally on the EVK.
17These are the HW changes required to run this test:
18 - Populate R2124, R2125
19 - Remove J99, J100
20 - Short Data J99-pin1 (SAI1_RX_DATA0) to J100-pin1 (SAI1_TX_DATA0)
21
22FRDM-MCXN947:
23This board uses CONFIG_I2S_TEST_SEPARATE_DEVICES=y and connects two SAI peripherals by shorting
24signals externally on the EVK. These are the HW changes required to run this test:
25 - Short BCLK J1-pin9 (SAI1_RX_BCLK/P3_18) to J3-pin15 (SAI0_TX_BCLK/P2_6)
26 - Short SYNC J1-pin13 (SAI1_RX_FS/P3_19) to J3-pin13 (SAI0_TX_FS/P2_7)
27 - Short Data J1-pin15 (SAI1_RXD0/P3_21) to J3-pin7 (SAI0_TXD0/P2_2)
28
29MIMXRT1060-EVK[B/C]:
30This board uses a single SAI and connects the TX and RX signals by shorting externally on the EVK.
31These are the HW changes required to run this test on MIMXRT1060-EVK[B/C]:
32- Remove jumper J99
33- Short BCLK J23-pin5 (SAI1_RX_BCLK / GPIO_AD_B1_11) to J23-pin23 (SAI1_TX_BCLK / GPIO_AD_B1_14)
34- Short SYNC J23-pin9 (SAI1_RX_SYNC / GPIO_AD_B1_10) to J23-pin16 (SAI1_TX_SYNC / GPIO_AD_B1_15)
35- Short Data J23-pin11 (SAI1_RX_DATA0 / GPIO_AD_B1_12) to J23-pin17 (SAI1_TX_DATA0 / GPIO_AD_B1_13)
36
37- NOTE: these connections cause contention with the following signals/features:
38 - camera CSI_D[2-7]
