- 1.大家好?TI技术人员你们好?是否有570 DMA相关数据接收的例程? 变长度和不变长度?或者SPI 相关也可以,我只找到一些发送的 没找到接收的。
- 2.我在调试SCI DMA 时候遇到一些问题,我的代码如下 :
- 3.目前出问题点
dmaRAMREG->PCP[channel].ISADDR = g_dmaCTRLPKT.SADD;,这个位置出现问题 ,
stmfd r13!, {r0 - r12, lr}; push registers and link register on to stack
ldr r12, esmsr3 ; ESM Group3 status register
ldr r0, [r12]
tst r0, #0x8 ; check if bit 3 is set, this indicates uncorrectable ECC error on B0TCM
bne ramErrorFound
tst r0, #0x20 ; check if bit 5 is set, this indicates uncorrectable ECC error on B1TCM
bne ramErrorFound2
noRAMerror
tst r0, #0x80 ; check if bit 7 is set, this indicates uncorrectable ECC error on ATCM
bne flashErrorFound
bl custom_dabort ; custom data abort handler required
; If this custom handler is written in assembly, all registers used in the routine
; and the link register must be saved on to the stack upon entry, and restored before
; return from the routine.
