ejtag_info->ejtag_ctrl variable. It was being overwritten by the value read back from the EJTAG CONTROL register. Because of the way this register works you do not want to use the value returned to write the register, you always want to write the bits explicitly. The second patch just reduces the DMA retries to 0 in anticipation of removing the retry code altogether. git-svn-id: svn://svn.berlios.de/openocd/trunk@1049 b42882b7-edfa-0310-969c-e2dbd0fdcd60
