From: Vladimir Vassilevsky on 23 Jun 2010 06:17 On TI OMAP-L138 DSP, there is a system register which contains "DSP reset vector" (HOST1CFG::DSP_ISTP_RST_VAL). For some reason, the lower 10 bits of this register are set to 0. Is this the address from which the DSP starts executing, or is this a pointer to memory location from which the DSP reads the starting address? I couldn't find any explanation in the docs. Presented this question to support; no answer. VLV

According to page 167 in SPRUGM7D (OMAP-L138 Applications Processor System: Reference Guide, April 2010) these bits are reserved. > Is this the address from which the DSP starts executing, or is this a > pointer to memory location from which the DSP reads the starting address? Maybe page 269 in SPRUGM7D gives a clue. bye Andreas -- Andreas H�nnebeck | email: acmh(a)gmx.de ----- privat ---- | www : http://www.huennebeck-online.de Fax/Anrufbeantworter: 0721/151-284301 GPG-Key: http://www.huennebeck-online.de/public_keys/andreas.asc PGP-Key: http://www.huennebeck-online.de/public_keys/pgp_andreas.asc |
