[beagleboard] Can't get SPI data up to 10 MHz - PRU

Hi, I need your help, I need to read data of an SPI Master device on the BeagleBone. Since the SPI kernel driver doesn't support an SPI slave mode I have to implement it in the PRU (Because the maximum frequency one BeagleBone's GPIO can be toggle is only 15 KHz). >From what I have read, the PR

[beagleboard] PRU - Can't read data up to 2.5 MHz

Hello, I need your help I have to read data from an SPI master device, which sends the clock at 10 MHz. Since the SPI kernel driver only allows to the beagle bone to working as SPI Master I had to implement this functionality using a PRU. >From what I've read throughout the internet the PRU pr

[beagleboard] How to acess shared memory between the PRU and Beagle Bone Black

Hi, I need your help, I am developing an application on the beagle bone for reading data for an SPI slave. For that, I have to use the PRU since the data transmission is up to 15 KHz. Following this tutorial: https://markayoder.github.io/PRUCookbook/ , in the *Chapter** 5 - Memory allocation

[beagleboard] Beagle Bone Black - trouble in setting-up the PRU (C++)

Hi guys, I need your help, the situation is the follows: I need to set up the beagle bone as SPI slave for reading data of a sensor, and since the kernel GPIO functions do not support very high frequencies I need to do that using the PRU. I am developing my application in C++ and I found this

Re: [beagleboard] Is cape manager obsolete? What about device tree overlays?

Hi I am having the same problem and can't solve it. Here is the output of "*sudo /opt/scripts/tools/version.sh "* *git:/opt/scripts/:[0aa8fd09a1821f6f9197aada6ec69e9746e91f67]* *eeprom:[A335BNLT00C05016BBBK1BDB]* *model:[TI_AM335x_BeagleBone_Black]* *dogtag:[rcn-ee.net console Ubuntu Image 2018-
