| 説明 | I2C debug port is working!!!!!!!!!!!!!!!!! As you can see this was done ages ago, it's only at the end of last year I resumed work on this.Getting I2C access and framebuffer access took two weeks of work during holidays (including many unsuccessful attempts at JTAG)...The Xtensa boot only took a week to get it to write to the framebuffer from the Xtensa code... It took much longer to get the newlib C library and RTOS (FreeRTOS) running on the Xtensa itself, register windows making CPU state save/restore a pain... |
