Part Number: AM4378
Hi,
I have two questions regarding AM437x Starter kit.
1) According to the schematic(sprr202,7page), in SD card interfance, MMC_D0, MMC_D1, MMC_D2 and MMC_D3 are pulled-up. But only MMC_D3 is pulled-down. I think this handling is for card detection.
But, in other sittara EVM(for example, TMDSSK3358 rev1.2, page 10), same MMC_D3 is pulled-up. Which is correct?
2) USB DP, DM : My customer measured the waveform of DP and DM by the differential probe. The amplitude of DP/DM is 0.9V. Is it no problem? It is usual level?
Please advise me.
I appreciate your quick reply.
Best regards,
Michi
