Part Number: AM4378 Hi,
Two DDR3L SDRAM 8bit are connected to the memory interface of AM4378. ① Is there any problem with the processing of empty terminals as follows? ・DDR_DQS2, DDR_DQS2 → Pull up to VDDS_DDR with 1kΩ ・DDR_DQSn2, DDR_DQSn3 →…
Part Number: AM4378 Hi AM4378 Champ !
My customer designed a Touch LCD circuit using the AM437x EVK schematic as a reference. The LCD is displaying fine, but the problem is that the touch-related waveforms appear to be strange. When I checked, there are…
Part Number: AM4378 Hi all.
I built boards based on the AM4378 EVM board. And I got into some problems.
First, the power supply of 1.8V is continuously maintained through the PMIC in the VDDS_RTC of the AM4378.
On Linux, we stored the time information…
Part Number: AM4378 My board uses the porz pin on the AM4378 (I think, I'm no EE and can't find a schematic) to indicate whether the board should BOOTP (an internal feature) or not. It's a jumper I set on the board. What I'd like to do is…
Hi Conor,
Conor said: How does AM437x automatically determine the CPU load situation?
This is in the kernel core, not related to AM437x itself, so I actually never looked into how kernel determine the CPU load, but I could imagine it might be based on…
Hi,
Would you be able to attach the device tree you are using? We are checking to see if the ethernet was disabled. Could you also please share any changes to made to the source and also let us know which specific sdk version is used.
Best Regards,

Part Number: AM4378 Hello,
We are doing SI analysis for DDR3L using sprm636a IBIS model. We need receiver thresholds parameters Tslew_ac, Vth, Vth_max, Vth_min, Vinh_ac, Vinh_dc, Vinl_ac & Vinl_dc for AM4378 DDR3L interface pins.
In IBIS model for…
