need detail bit-band description of SRAM.(both 871 and 809) Now only GPIO can be operated in 0x42000000 bit band region correctly. SRAM cannot. We test in several ways, but no result. You can contact me through QQ 8277717.
the sram address is from 0x00010000 to 0x00070000(XR809), and this area does not support bit-band access
do you have the iOS source codes for the sound wave
