Hello,

While trying to enable the SRAM retention for Sleep and Deep-sleep mode I’ve noted an unexpected behavior. In the RV32M1 Reference Manual Rev. 1.1 It is said that SRAMLPR and SRAMDSR are used to enable the SRAM retention, however, when I try to write directly on these registers, my program stops. Although they are correctly defined in t…[Read more]

Hi Jason_Yu,

I had not noticed that for the GPIOE the registers are also aliased to the IOPORT interface through FGPIOE. Retesting it calling CLOCK_EnableClock(kCLOCK_Rgpio1) solved the problem.

Thank you!

Hello Alex,

Thank you for your answer. In fact, in order to configure the pin as GPIO I`m using the function PORT_SetPinConfig() in pin_mux.c whit the following struct :

const port_pin_config_t porte8_pinP16_config = {
kPORT_PullUp,
kPORT_FastSlewRate,…[Read more]

Hello,

Based on the example gpio_input_interrupt (found in the folder driver_examples of the SDK) I`ve been trying to add another switch from the board in order to make an simple code where one switch is responsible for turning the LED on and the other for tuning it off. Even after making the necessary changes I have always a problem with the…[Read more]

Hello,

I`m trying to run the demo applications for the cortex ARM following the instructions on Getting Started with RV32M1 SDK ARM, but in section 5.3 it says to “download the Jlink patch for RV32M1 from open-isa.org”. Looking into your website, I could not locate the link to download the patch. Could anyone send it here, please ?

Thank you.

Hello JC Pacheco,

Do you know if there is a special reason for the implementation of the BLE applications on multi-core ? I mean, in terms of performance or interfacing with the radio controller. I`ve seen other BLE applications running only in ZERO-RISCY, but none that runs only in RI5CY core. I imagine that using the Message Unit to control…[Read more]
