For i.MX1 you need the LINUX_BSP_0_3_6 or 0_3_8 depending in which ADS board version do you have. new newer ones (2.0) need 0.3.8. Inside the BSP have all info needed. Only take tare w/ 0.3.8 on installing the toolchain. If you do not need running the application in your PC based linux system do not run the ldconfig -v command after toolchain instalation, if your system is not a Red Hat 7.2 it could be damage by issuing this command.
