Dear TI Experts,
My customer is designed TM4C1290NCPDT in their product and it has been in MP stage over 1 year. In the past, they referenced TM4C129X Development Board, choosed a 25MHZ crystal for main Oscillator with 2pcs 10pF load capacitance. Recently, they changed another crystal brand and found that the TM4C1290 didn't work. After check the datasheet of TM4C1290 again, they found that the "External load capacitance for Main Oscillator" is shown as 12~24pF in the datasheet, so they changed the C1/C2 to 20pF and TM4C1290 works again, however, they are worried about if there will be potential risk on the 10pF version TM4C1290 board which they have shipped to market before.
Could you kindly help to advise if customer should recall their shipped TM4C1290 board and change 10pF load capacitance to 12~24pF? Thanks a lot.
