## Summary * arch/risc-v/espressif: Bump common source version This PR bumps common source version for RISC-V-based Espressif SoCs on NuttX. Specifically, this solves an issue regarding SPI flash frequency selection on ESP32-C6. Although 80MHz is the [default frequency](https://github.com/apache/incubator-nuttx/blob/d7dabc90f6cc2ec721372009d4ceff23c9f6c6f7/arch/risc-v/src/common/espressif/Kconfig#L1464) for the SPI flash, it isn't being set properly, as shown on testing section. ## Impact Impact on user: YES. Applications may run faster if the correct frequency is set. Impact on build: NO. Impact on hardware: YES. It sets the correct frequency for the SPI flash. Impact on documentation: NO. Impact on security: NO. Impact on compatibility: NO. ## Testing This common source update fixes a known issue regarding SPI flash frequency on ESP32-C6. Before and after logs are provided as evidence for it. Build, flash and run the firmware on ESP32-C6 according to the following instructions: ### Building ``` make -j distclean && ./tools/configure.sh esp32c6-devkitc:spiflash && kconfig-tweak -e DEBUG_FEATURES && make olddefconfig && make flash ESPTOOL_PORT=/dev/ttyUSB0 -j$(nproc) ``` ### Running ``` picocom -b 115200 /dev/ttyUSB0 ``` ### Results Compare the boot lgo before and after applying this patch and check the SPI flash frequency: #### Before ``` *** Booting NuttX *** I (47) boot: chip revision: v0.1 I (47) boot.esp32c6: SPI Speed : 40MHz I (47) boot.esp32c6: SPI Mode : DIO I (48) boot.esp32c6: SPI Flash Size : 4MB ``` Note: 80MHz was expected! #### After ``` *** Booting NuttX *** I (47) boot: chip revision: v0.1 I (47) boot.esp32c6: SPI Speed : 80MHz I (47) boot.esp32c6: SPI Mode : DIO I (48) boot.esp32c6: SPI Flash Size : 4MB ``` 80MHz is set as expected. -- This is an automated message from the Apache Git Service.
