Part Number: UCD9222 Other Parts Discussed in Thread: UCD7242 背景:
采用UCD9222+UCD7242的架构给DSP供电产生两轨rail1 rail2的电压 CVDD和 VCC1V0,采用的原理图参考了经过验证的项目的原理图,器件参数相同,但接地部分有改动,由参考设计的单一地修改到了分割地,且发现了接地错误,7242的接地都弄错成数字地(DGND)了。12V的电源本应是对应功率地(PGND)的,PGND与DGND只通过0402封装的0欧电阻连接…
Part Number: TAS5558 Hello!
We are currently developing a digital audio system, initially using the TAS5624DDVEVM for decoding and power amplification. Currently, the interface section uses the Input-USB Board3 based on TAS1020B. However, the TAS1020B…
Part Number: TLV320AIC3204 这是我的寄存器配置

Part Number: DLPC350 Other Parts Discussed in Thread: DLP4500
原因:DLP4500方案(DLPC350ZFF),由于 M29DW128GL70N停产买不到料,更换为 MT28EW128ABA1LJS-0SIT
问题:使用JTAG flash programmer烧录bootloader后,显示烧录成功,但无法启动,连接USB不成功。
请教下是否需要bootloader对此flash进行适配?还有其他问题导致? MT28EW128ABA1LJS…
