Hello, all. I'm sorry for stupid questions. I look at imx35.cfg and see these lines: --- # No IDCODE for this TAP jtag newtap $_CHIPNAME whatchacallit -irlen 4 -ircapture 0 -irmask 0x0 -expected-id 0x0 jtag newtap $_CHIPNAME sdma -irlen 5 -ircapture 0x1 -irmask 0x1f -expected-id $_SDMATAPID ---
Then, when I run the command scan_chain, I see: --- > scan_chain TapName Enabled IdCode Expected IrLen IrCap IrMask -- ------------------- -------- ---------- ---------- ----- ----- ------ 0 imx35.etb Y 0x2b900f0f 0x2b900f0f 4 0x01 0x0f 1 imx35.cpu Y 0x07b3601d 0x07b3601d 5 0x01 0x1f 2 imx35.whatchacallit Y 0x00000000 0x00000000 4 0x00 0x00 3 imx35.sdma Y 0x0882601d 0x0882601d 5 0x01 0x1f --- Thus, the sequence of TAP-s: etb-> cpu-> whatchacallit-> sdma, if I understand correctly. But Freescale Support once sent him a letter stating the following: --- ... i.MX35 has 4 devices on it's JTAG scan chain as follows : TYPE IR length ------------ ------------- ETMBUF 4 ARM11 5 SDMA 4 SJC 5 --- Is there somewhere errors imx35.cfg?
