If you have a module with revision **< PROTO1 Rev. 0102**, the following must be done in order to build the BSP, since early release samples of TQMa93xx use i.MX93 chip revision **1.0**. \\
\\
The[[https://www.nxp.com/webapp/Download?colCode=AN13997|AN13997 Migration Guide from i.MX 93 A0 to A1]]
lists differences between A0 to A1 parts. An alternative description is "Sillicon Rev" 1.0 and 2.0 as mentioned in Figure 1 "Part number nomenclature - i.MX93" in Datasheet Rev. 3 12/1023. \\
\\
A0 and A1 need a different sentinel firmware files, defaulting for A1.
In order to set the older firmware, add the following line to `conf/local.conf`: \\
\\
<code>
IMX_SOC_REV = "A0"
</code>
