RE: RZ/A1 RSK Device Tree add WiFi/BT using SDIO interface with TI Wilink8
Hi Chris,Yes the driver is calling request_irq() - but I need to set that value. The following code is what I added to the board-rskrza1.c. I've removed the ethernet phy from the RSK and soldered a...

Hi jdseymour,Did you setup WE0# (P7_6) pin to program a flash chip on CS0?RZ/A1 doesn't setup this pin at reset.

Thanks. For a minute, that sounded really promising! But, alas, that pin is set up correctly.Related question: If I screwed up the MMU settings and accidentally left this area as "Read-Only", would a...

My design executes code directly out of a flash chip on CS0. Now I need to be able to erase and program a portion of this chip for logging purposes.I wrote a simple routine to query the flash chip's...

Hi,Is type of flashAddr correct?volatile uint16_t *flashPtr = (uint16_t *)flashAddr;I think it's:volatile uint16_t **flashPtr = (uint16_t **)flashAddr;Regards,

Thanks. So far, I've checked my pin configuration, the MMU settings, and the CS0 settings. Everything seems correct - except I'm not getting pulses on the WE# line when I write to the flash.I'll keep...

Does anyone here know about write-back vs. write-through caching?I'm wondering if caching is tripping me up. I found that my flash space was set in the MMU as "write-back", but when I changed it to...

If you look at the Renesas 3.14 BSP, you'll notice that we didn't use the "EDT-FT5X06" driver (drivers/input/touchscreen/edt-ft5x06.c) that was already in the kernel. Instead, we made one.The reason is...

Hi all!I'm working on a RZA1H based board. For demo purposes I'm trying to use the LCD touchscreen panel that came with the RZA1H starter kit +. I managed to show images on the screen, but I'm...

Thank you for your answer.I did as you suggested: I copied the driver's package folder, updated all files needed to enable the driver selection through menuconfig and it compiled.I also copied...

Thank you Chris, this helps alot. I can bring up the interface, however I am receiving roughly ~3000 interrupts a second when looking under /proc/interrupts even though the scope only shows the initial...

If you keep getting interrupts over and over again, I would guess the interrupt is set to level instead of edge.Note that the i2c driver can't set the edge/level (restriction of use the ARM GIC...

Sorry...I just read what I wrote and that doesn't make any sense!In the code above....we're setting it to LOW LEVEL because the touchscreen controller will keep the line low until all the touches have...

Hi Chris,Thanks for the response! I agree I think the interrupt is configured wrong. I did set ICR1 to AAAA in an attempt to force all IRQs to rising edge triggered because it did not seem to help when...
