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…

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…
