i have the same problem with SSP and DMA
Im using a release build, with a connected debugger it is all fine but without the transfer doesnt work
when i start the board with a debugger and deplug it during running all is fine, even after reset is fine, only with a complete power down this happens
Hi, I have same problem with LPC1754, also.
Dma transfers a memory data buffer to ssp0, with bus width 16 or 32 bit: with debugger the system run ok (I can disconnect the debugger and to reset the board, and this continue to run), but at power up without debugger the system not works correctly: it seems that the dma lose data. I checked that the source buffer remains uncorrupted.
How did you solve your problem?
Thanks.
