外挂SPI RAM(PSRAM)出现test fail问题
Posted: Tue Jul 14, 2020 1:10 am
我正在使用ESP32-PICO-KIT_V4.1 板子外挂8M的PSRAM,IO按参考设计接法如下:
psram_pin1(CS):-->esp32 gpio10
psram_pin2(SO/SIO1):-->esp32 gpio17
psram_pin3(SIO2):-->esp32 gpio7
psram_pin4:-->gnd
psram_pin5(SI/SIO0):-->esp32 gpio8
psram_pin6(SCLK):-->esp32 gpio6
psram_pin7(SIO3):-->esp32 gpio11
spiram_psram.c文件中修改引脚定义如下:
#define PSRAM_SPIQ_SD0_IO 17
#define PSRAM_SPID_SD1_IO 8
#define PSRAM_SPIWP_SD3_IO 7
#define PSRAM_SPIHD_SD2_IO 11
idf版本:
v3.3.2-270-gf4333c8e3
编译工程示例:hello_world
menuconfig 中打开SPI RAM 支持,配置CS为gpio10
出现的错误log如下:

看上去好像检测到psram了,但是为什么会出现test fail呢?各位帮忙看看,多谢!
