Re: LTC Connector DE10-Standard FPGA
Hi greenlantern01, Regarding the GPIO toggling not working , probably you can check whether R306 is the same placement as per rev C. Unfortunately i dont have Rev B schematic so cannot confirm on this whether the connections are the same with Rev C. Probably you will need to toggle the LTC first before can use the i2cdetect. Thanks Regards Kian13Views0likes1CommentRe: Mandelbrot viewer on Cyclone V - Platform Designer layout
Thanks EV for the support. Hi Fred, Just wondering about the status for this case? Do you require further help , otherwise I would like to set this case to closure and transition to community support.

Thanks Erica for the advice on this issue. Hi Sarah, Since you mention that Linux is working and the OS that you're using is not, as Erica mentioned, I would suspect the device tree is not set properly for your OS, could you check on this first to see whether it is configured correctly, probably you can compare with the Linux since that is working. Thanks Regards Kian16Views0likes0CommentsRe: LTC Connector DE10-Standard FPGA
Hi greenlantern01, You can get the schematic from the DE10-standard cd rom from this link https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=165&No=1081&PartNo=4#contents In the zip folder there is a folder "Schematic" which contains both Rev C and Rev D schematic. You will need to register an account with Terasic though before you can download. Thanks Regards Kian10Views0likes0CommentsRe: LTC Connector DE10-Standard FPGA
Hi greenlantern01, Really sorry for the delay in getting back, was going through my mails after back to office , missed out on the notification. From the screenshot, seems it is resetting during kernel loading stage, probably some settings in the dts. I was checking back on Terasic schematic and notice that there is some differences between DE10-Standard Rev C and Rev D board. Could you help confirm you board revision ( i suppose to be rev C because in schematic I still see the digital accelerometer and HPS_LTC_GPIO connected to TS3A5018, Rev D schematic all these been removed) Anyway if you're on Rev C, disregard the DTS changes you made first, and 1. Measure the HPS_LTC_GPIO ( can probe R306 resistor and check whether it toggles or switch just to check the pin logic ) I got this from the TS3A5018 datasheet (but the table here seems to indicate the other way round for NO/NC) From schematic, Gsensor/ digital accelerometer is connected to I2C1 which looks like it is connected to different pin all together , not via TS3A5018 , thus you always can talk to Gsensor regardless of the LTG connector. After verifying the LTC_GPIO toggles correctly, probably can check whether Linux side have these i2C drivers already initialized, if yes maybe no need add the i2c2 in the DTS for linux-socfpga Try this command to list the i2c : i2cdetect -l You should see something like Synopsys DesignWare scan the bus to see whether gsensor and your ltc shows up i2cdetect -y -r <bus number from the list, 0,1,2> This one to confirm that i2c has gsensor and your LTC device connected.

Hi Keloke98, I will be out of office starting next week, thus response will be slower. Please do try to execute the steps to build the uboot till the creation of the sdcard.img , if everything works , you should see that you are using a new uboot version instead of the old one. Thanks Regards Kian26Views0likes0Comments
