I browsed a source codes of OpenOCD and would like to ask any experts A file mips32_dmaacc.c
says: The following logic shamelessly cloned from HairyDairyMaid's wrt54g_debrick * to support the Broadcom BCM5352 SoC in the Linksys WRT54GL wireless router * (and any others that support EJTAG DMA transfers). So it should supports DMA_access. BUT uses 17th bit ( defines it as EJTAG_CTRL_DMAACC ) of ejtag control register bits ECR But EJTAG specification 2.6 or 3.1 says about that 17th bit "Must be written as zeros; return zeros on reads." and is not marked as DMA access bit How was found out (it is nescessary) to use that bit for the DMA access? and does anyone has ever used this OpenOCD for MIPS DMA access?
